(-1,-8) is a solution

Work Step by Step

We are given that $y=3x-5$. 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 (0,5): $3\times0-5=-5\ne5$ So, (0,5) is not a solution. For (-1,-8): $3\times-1-5=-8$ So, (-1,-8) is a solution.
