Answer:
-4
Step-by-step explanation:
The formula to find the slope is (change in y)/(change in x). In other words, rise over run.
If we look at the data, we can see that the x and y value changes.
x value: -3 --> -2 --> -1 --> 0 --> 1
y value: 12 --> 8 --> 4 --> 0 --> -4
When y changed from 12 to 8, the x changed from -3 to -2.
y: 12 --> 8
x: -3 --> -2
There was a difference of -4 in the y and a difference of 1 in the x.
At the top, I wrote that the slope was (change in y)/(change in x)
With -4 and 1 we found, we can say that the slope is -4/1.
If we simplify this answer, we end up with -4.
So -4 is the slope of the data.
