Algebra-1

From the graph, we can see the two coordinates (-1, -8) and (1, 8). These coordinates represent two points on the graph.

To find the slope of the line, we can use the formula:

slope = (change in y) / (change in x)

The change in y is the difference in the y-coordinates between the two points. In this case, the y-coordinate of the second point (8) minus the y-coordinate of the first point (-8) gives us a change in y of 8 - (-8) = 16.
