Enter your answer in the boxes

Answer 1

A(8, 10)

Explanation:

Vertex A is on the vertical line x=8, so we can find the y-coordinate by solving the boundary equation ...

5x +8y = 120

5(8) +8y = 120 . . . use the x-value of the vertical line

5 + y = 15 . . . . . . . divide by 8

y = 10 . . . . . . . . . . subtract 5

Point A is (8, 10).
