Answer:
-3/5
Explanation:
To find the slope of a line on a graph, look for the amount of spaces up/down and left/right one point moves to get to the other.
Moves right or up are positive, and moves left or down are negative. When one move is negative, for example, right and down, the slope is negative. When both are positive or both are negative, the slope is positive.
The amount of moves up/down are the numerator of the slope, and the amount of moves left/right are the denominator of the slope.
In this example, the point on the left moves 3 spaces down and 5 spaces to the right. This means the slope is -3/5.
Note: It may seem hard to follow, but try to understand. It'll get easier!
