# How do you determine whether (-1, -1) and (1, -1) is a solution to y > x - 2 ?

Jul 19, 2015

$\left(- 1 , - 1\right)$ is a solution to $y > x - 2$.

$\left(1 , - 1\right)$ is not a solution.

#### Explanation:

Substitute the values into the inequality.

First Possible Solution

$\left(- 1 , - 1\right)$

$y > x - 2$ =

$- 1 > - 1 - 2$ =

$- 1 > - 3$

This is a correct statement.

$\left(- 1 , - 1\right)$ is a solution for this inequality.

Second Possible Solution

$\left(1 , - 1\right)$

$y > x - 2$

$- 1 > 1 - 2$

$- 1 > - 1$

This is an incorrect statement. $- 1 = - 1$

$\left(1 , - 1\right)$ is not a solution for this inequality.
