Answer:
-1
Explanation:
The slope is the change in y over the change in x. In this graph, the y-value decreases by 1 unit to the right, and the x-value increases by 1 unit. So, this means that the slope is represented as -1/1. This can then be rewritten as -1.
We know that this slope is negative because it decreases to the right. Positive slopes increase to the right.
