Which equation could you use to solve for x in the proportion 4 over 5 = 9 over x ?

Step-by-step explanation:

4/5 = 9/x

x(4/5)= 9

4/5x = 9

×5/4 ×5/4

x=11.25

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
