Question

What is the solution to the system of equations below?

y=-1/2x+6 and y=-3/4 x-4
(-8,2)
(-8,-1)
(8.10)
(8.-10)
•

Answer 1

(-8, 2)

Explanation:

set these equations equal to each other

1/2x + 6 = -3/4x -4

5/4 x = -10

x = -10x4/5 = -40/5 = -8

plug this x into one of the equations

y = 1/2 (-8) + 6

y = -4 + 6

y = 2
