Question

7. Use substitution. What is the

solution of the system of
equations?

y = -4x + 11
8x + 2y = 14

A. X = 6, y = 7
B. x = 6, y = -7
C. Infinitely many solutions
D. No solution


PLEASE HELP AND PLEASE LOOK AT THE OTHER QUESTIONS I ASKED

Answer 1

No solution, D

Explanation:

If you rewrite the second one to be the y=mx+b form then you get

8x-14= -2y

Divide by -2 and get

-4x+7=y

Because the slopes are the same the lines will never intersect which means there is no solution
