On your paper, copy and complete each $x→y$ table below. Using what you know about $m$ and $b$, write an equation that represents the data in the table. Homework Help ✎

1.  x y 0 1 2 3 4 30 200 x 5 7 9 11 13 505

Look for a connection between the input and the output. Use the equation $y=mx+b$ as a guideline.

What is the starting point? ( $y$-intercept )

What is the growth rate?

1.  x y 0 1 2 3 4 30 150 300 x 4 2 0 –2 –4

Follow the steps in part (a).
