5.1 Writing Linear Equations in Slope-Intercept Form

Author: Christine L

Slope-Intercept Form: y=mx+b

b= y-intercept

m= slope

To find the slope when two points are given use:

Example:

The slope in the case is 3/2 or 1.5.

Then you would use on of the points given and plug it into the equation. (3,4)

4=1.5(3)+b

4=4.5+b

b=8.5

Your final answer would be:

y=1.5x+8.5

In this video there are people singing a song to YMCA but are explaining Y=MX+B. It is a fun way to remember slope-intercept form.

In this slide show it shows you how to write linear equations in slope-intercept form and gives you some problems to try yourself.
