4.2 Today we will learn how to graph the line of an equation by using a table of
values:
First we need to get the equation in Slope-Intercept Form: (same as solving for y)
Standard Form:
Slope-Intercept Form:
Ax + B

Before we made a table of values to graph a line,
but actually all it takes is TWO POINTS to make a line.
So, today we will
use two VERY CONVENIENT points
to find graph the function
The X intercept
The point where the
line c
