Question

Decide whether the given ordered pair is a solution to the system of equations.

y = −4x
y =1/2x+7
(-2,8)

Answer 1

No, the ordered pair is not a solution to the system of equations

Explanation:

Plug x and y into the equations and if both equations are true, then the ordered pair is a solution. Y is 8 and X is -2

8 = -4(-2) is correct

8= 1/2(-2) + 7 is not correct, the equation is equal to 6, not 8.
