4-97.

A line intersects the graph of y = x2 twice. One point has an x-coordinate of $−4$, and the other point has an x-coordinate of $2$. 4-97 HW eTool (Desmos). Homework Help ✎.

1. Draw a sketch of both graphs, and find the equation of the line.

2. Find the measure of the angle that the line makes with the x-axis.

Draw a slope triangle between the two points. Find the measure of the angle that corresponds to the angle the line makes with the x-axis using $\tan^{−1}(?)=θ$.

$63.4° (\text{ or } 116.6°)$
