Question

computing a missing coordinate hank draws a line with a zero slope through the points (-2, 4) and (3, b). which value of b could represent hank’s second point?
options: -3, -1, 4, 9
click or tap the graph to plot a point.

Explanation:

Step1: Recall zero slope property

A line with zero slope is horizontal, so all points on the line have the same $y$-coordinate.

Step2: Match the y-coordinate

The first point has $y=4$, so the second point's $y$-coordinate $b$ must equal 4.

Answer:

4
