Which statement justifies the given ordered pair as a solution to the system of equations? (-1, - 13) {y=3x-10y=-2x-15

These are the four statements that come with the question and from which you have to select the right one.

A) - 1=3 (-13) - 10

-1=-2 (-13) - 15

B) 13=3 (1) - 10

13=-2 (1) - 15

C) 1=3 (13) - 10

1=-2 (13) - 15

D) - 13=3 (-1) - 10

-13=-2 (-1) - 15

The answer is the option D.

Just replace the values x = - 1 and y = - 13 in the two equations and you obtain the answer:

1) y = 3x - 10 = > - 13 = 3 (-1) - 10

2) y = - 2x - 15 = > - 13 = - 2 (-1) - 15
