Question

Solve the system of equations y = -5x - 7 and 5x + y --3 using a graphical method.

A) (-1,-2)
B)
(59
C)
(1.-12)
Eliminate
D)
no solution

Answer 1

D

Explanation:

The answer is D because the two equations have the same slope, but different y intercepts

Answer 2

5(2)-y = 1

10-y = 1

y= 9

-2(2) + 9b=59

9b= 59+4

9b=63

b=7
