Question

If the ordered pair (-5/2, y) lies on the graph of y = 7 - 2x, find the value of y.

2
19/2
12

Answer 1

y = 7 - 2(-5/2)

y = 7 + 5

y = 12

Answer 2

y = 12

When x = -5/2, y = 12

Step-by-step

Just put in -5/2 for x in the equation y = 7 - 2x and solve for y.

y = 7 - 2(-5/2)

y = 7 + 5

y = 12
