Answer:

(1, - 5)

Explanation:

To determine which ordered pair is a solution

Substitute the x value into the right side of the equation and if the value is equal to the y- coordinate of the point then it is a solution.

(1, - 5)

y = - 4(1) - 1 = - 4 - 1 = - 5 ← True

(4, 15)

y = - 4(4) - 1 = - 16 - 1 = - 17 ≠ 15

(2, - 7)

y = - 4(2) - 1 = - 8 - 1 = - 9 ≠ - 7

(- 5, 1)

y = - 4(- 5) - 1 = 20 - 1 = 19 ≠ 1

(1, - 5) is a solution to the equation y = - 4x - 1
