Using slope intercept form is one of the quickest and easiest ways to graph a linear equation.
We need to define:
x intercept is the point (
,
) where your line crosses___________________.
y intercept is the point ( ,
) where your line crosses ___________________.
We are only going to focus on the y intercept in this lesson, but you'll need to know x intercept later.
Examples:
Recall:

_ ______________________________
___ and ____ are your variables.
______ = slope.
_____ = y-coordinate of the y-intercept.
.
In this form only (y = mx +b) the __________of x is the slope and the __________ is the y intercept
