(-6,0) is not a solution
Work Step by Step
Use the ordered pair (-6,0). X=-6. Plug it into the equation: $y=-2(x+3)$ $$y=-2(-6+3) = -2(-3) = 6$$ Remember that y=0 in the ordered pair, in this equation when the value of -6 equals x, the y value was 6. Therefore, the coordinate (-6,0) is not a solution.
