2-102.

Write the equation for the line containing the points listed in the table below.

 $x$ $–1$ $1$ $3$ $5$ $y$ $2$ $16$ $30$ $44$

Find the rate of growth per unit. This is the slope.
Do this by finding the pattern in the graph, or by plotting two of the points and making a slope triangle.

If $−1$ is $2$ and $1$ is $16$, what is $0$?
This is the $y$-intercept. Use it along with the slope to write a $y = mx + b$ equation.

Use the eTool below to write the equation for the function in the table.
