(A): 7
(B): 12
A.)Correct.
To find the corresponding y-value when the x-value is 3, find 3 on the horizontal axis, and go up until you find the coordinate point. This matches with 7 on the
vertical axis. To find the corresponding x-value when the y-value is 9, find 9 on the vertical axis, and go over until you find the coordinate point. This matches with
17 on the horizontal axis.
Correct
