Which statement describes the relationship between x and y? a. as x increases, y decreases. b. as x increases, y increases. c. as x increases, y increases and then decreases. d. as x increases, y decreases and then increases.

Option: D is the correct answer.

D.  As x increases, y decreases and then increases.

Clearly from the graph of the function we could see that as the x-value increases the y-value decreases as the graph is a  line segment whose slope is negative and then it increases  since the graph is again a straight line with a positive slope .

Hence, the statement that best describes the relationship between x and y is:

D.  As x increases, y decreases and then increases.

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9
