Slope Intercept Form
There are two main steps to getting the slope-intercept form of a line - and they're in the name. We need to first find the slope, and then find the y-intercept.
You can read the steps below, or you can scroll down to our calculator (you know you want to)
and try it out yourself 😎.
Slope-Intercept FormulaThe slope-intercept form of a line looks like this: stands for the slope and stands for the y-intercept of the line. The steps to write this equation are below.
- First, find two points on the line. Let's call them Point 1 with coordinates and Point 2 with coordinates .
- Once we have our two points, we'll find the slope. Divide the change in by the change in :
Notice the color coding - make sure that the first and values in the subtractions are from the same point.
- Now, let's pretend that the value we got for is . We can plug that back into our equation, so now we have
To get , we just plug in one of our points -
- and solve for .
