(1,5) is a solution.
Work Step by Step
We are given that $y=-2x+7$. In order to see whether each ordered pair is a solution of the given equation, we can plug in the ordered pair to the equation. For (1,5): $-2\times1+7=5$ So, (1,5) is a solution. For (-2,3): $-2\times-2+7=11\ne3$ So, (-1,-8) is not a solution.
