Question

Which ordered pair is the solution to the system of linear equations y = - 7 x + 2 and y = 9 x - 14?

(- 5, 1)
(1, -5)
(5, - 1)
(- 1, 5)

I found another page exactly like this, but the person put one instead of fourteen and so the correct answer was not given.

Answer 1

(1,-5)

Explanation:

set the equations equal to each other and solve. this gives you a solution of x=1 which if you put into the equation gives you y=-5. Therefore, (1,-5)
