Question

use the following graph to find x when y = -1. when y = -1, x =

Explanation:

Step1: Locate y = -1 on y - axis

Find the horizontal line where \( y=-1 \) on the graph.

Step2: Find intersection with the line

Identify the point where this horizontal line intersects the given blue line. Then, find the corresponding x - value of that intersection point. From the graph, when \( y = - 1 \), we can see that the x - value at the intersection is 3.

Answer:

3
