Answer:

  {(0, −5), (2, 9), (−3, −26)}

Step-by-step explanation:

You only need to try the first point in each set to eliminate the wrong answers.

a: 7(-5)-5 = -40 ≠ 0

b: 7(2)-5 = 9 ≠ 7

c: 7(0)-5 = -5 . . . matches given point

d: 7(1)-5 = 2 ≠ 3

The third choice is the correct one: {(0, −5), (2, 9), (−3, −26)}.
