Answer:
No, ordered pair is not a solution to the system of equations.
Explanation:
y = -4x
substituting (-2, 8)
8 = -4(-2)
8 = 8
therefore the point satisfies this equation
y = (1/2)x + 7
8 = (1/2)-2 + 7
8 = -1 + 7
8 = 6 (false)
therefore point doesn't satisfy second equation.
Hence ordered pair is not a solution to given system of equations.
