Which of the following graphs is decreasing for all values of x?

a. x
b. y
c. w
d. z

I'm not sure which graph corresponds to what letter, but the graph that starts in the upper left corner and goes to the bottom right corner (the second one) is correct.

This graph shows that it has decreasing values of x.

Let me know if this helps!

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

2

x+10
