It’s D, because the x-value, 8, has two y-values, the 5 and 9. In order to be a function, each x-value has to have only one y-value.
Answer:
Y2-y1/x2-x1
=2-(-6)/2-(-2)
=8/4
=2
Step-by-step explanation:
Given two points of a line to find the slope we use the formula; y2-y1/x2-x1 Hence the answer above.
