11-85.

Paula graphed a line and found that $f\left(-2\right)=5$ and $f\left(0\right) = 2$. Graph this line and find its equation.

$f\left(-2\right)=5$ means $\left(-2,5\right)$ is a point on the line. Also, $\left(0,2\right)$ is a point on the line.

Graph the points on a set of axis, then draw the line.

To find the equation, make a slope triangle to find the slope and the $y$-intercept. Substitute these values into the equation of a line.
