(-1,2) is a solution.

Work Step by Step

We are given that $y=2|x|$. 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 (-1,2): $2\times|-1|=2\times1=2$ So, (-1,2) is a solution. For (0,2): $2\times|0|=2\times0=0\ne2$ So, (0,2) is not a solution.
