3.5 – Write and Graph Equations of Lines
Linear equations may be written in different forms. The general form of a linear equation in slope-intercept form y = mx+b, where m
is the slope and b is the y-intercept.

Can solve in either of two ways:
OR
Plug in m, x, and ySolve for b.
Then, plug back into the equation m and b.
Solution:
