You may already be familiar with the "y=mx+b" form (called the slope-intercept form of the equation of a line). It is the same equation, in a different form! The "b" value (called the y-intercept) is where the line crosses the y-axis. So point (x 1, y 1) is actually at (0, b) and the equation becomes:
2/26/2017 · Point-slope is the general form y-y₁=m(x-x₁) for linear equations. It emphasizes the slope of the line and a point on the line (that is not the y-intercept). Watch this video to learn more about it and see some examples.
Using the Point-Slope Form of a Line Another way to express the equation of a straight line. Point-slope refers to a method for graphing a linear equation on an x-y axis.When graphing a linear equation, the whole idea is to take pairs of x's and y's and plot them on the graph.
One type of linear equation is the point slope form, which gives the slope of a line and the coordinates of a point on it. The point slope form of a linear equation is written as . In this equation, m is the slope and (x 1, y 1) are the coordinates of a point. Let’s look at where this point-slope formula comes from.

Write equations in point-slope form given two pairs of values, and convert the equation into slope-intercept form. If you're seeing this message, it means we're having trouble loading external resources on our website. If you're behind a web filter, ...
There are two conventional ways of writing the equation of a straight line: point-slope form and slope-intercept form. If you already have the point slope of the line, a little algebraic manipulation is all it takes to rewrite it in slope-intercept form.
Finding the Equation of a Line Given a Point and a Slope. If we have a point, , and a slope, m, here's the formula we : use to find the equation of a line: It's called the point-slope formula (Duh!) You are going to use this a LOT! Luckily, it's pretty easy -- let's just do one: Let's find the equation of the line that passes through the point ...
Point-slope form is about having a single point and a direction and converting that between an algebraic equation and a graph. Examples: Find the equation of the line that passes through (-3, 1) with slope of 2.
Horizontal Lines. The equation of a horizontal line is y = b where b is the y-intercept.. Since the slope of a horizontal line is 0, the general formula for the standard form equation , y = mx + b becomes y = 0x +b y = b.Also,since the line is horizontal, every point on that line has the exact same y value.
point-slope form calculator - step by step calculation, formula & solved example to fit the point slope form of a line on a two dimensional space or XY plane. Point Slope Form. It is line geometry function mathematically defined by the formula (y - y 1) = m(x - x 1).
A line is uniquely defined by its slope and an arbitrary point on it. In the slope-intersect form this point on the line is either taken as the intersection (,) with the -axis, or the intersection (,) with the -axis and is combined with the slope , provided its existence, to establish the equation for the according line.
Use our Calculator. You can use the calculator below to find the equation of a line from any two points. Just type numbers into the boxes below and the calculator (which has its own page here) will automatically calculate the equation of line in point slope and slope intercept forms
The letter m in the point slope form equation is a number that represents the slope of the line. Some people refer to the slope as rise over run. Recall that if we have two points, then we are able to find the slope of the two points by using the slope formula.
Equation of a straight line can be calculated using various methods such as slope intercept form, point slope form and two point slope form. Two Point form is one such method used to find the equation of a straight line when there is no slope and the straight line is in a …
Point-Slope Form of a Line. Basically, the point-slope form is derived from the concept of finding the slope of a line when two points are given. In other words, if you can remember the slope formula then the point-slope form should naturally come to you.
Learn how to write the equation of a line using point-slope form, represent equations in both slope-intercept and standard form, and find the line that passes through a point and is parallel or perpendicular to the graph of a given equation.
Equation of a line: Slope-intercept form- Level 1. Based on the point and the slope provided for each question, apply point-slope formula to find the equation of a line and express the equation in slope-intercept form: y = mx + b.
Using the point-slope form of a line, how do you find the equation of the line that passes through the point (2,1) with slope -2/3? Would the X-intercept be 3 or 3.5? and then the slope...I just need help.
Write an equation in point-slope form of the line graphed below. (Use the right hand point) Write an equation in point-slope form of the line that passes through the two points given. Use the first point to write the equation. (4,7) and (5, 1) (9, -2) and (-3, 2) (3, -8) and 7(-2)
From here, the equation can be converted to either slope-intercept or standard form. Note that a horizontal line passing through a given point has the equation y = the y-coordinate of the given point, and a vertical line passing through a given point has the equation x = the x-coordinate of the given point.

Graphing - Point-Slope Form Objective: Give the equation of a line with a known slope and point. The slope-intercept form has the advantage of being simple to remember and use, however, it has one major disadvantage: we must know the y-intercept in order to use it! Generally we do not know the y-intercept, we only know one or more
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.. If you a point that a line passes through, and its slope, this page will show you how to find the equation of the line.
There are a few different ways to write the equation of a line. One of the most common ways is called "slope-intercept" form. It's called this because it clearly identifies the slope and the y-intercept in the equation. The slope is the number written before the x. The y-intercept is the constant written at the end.
