Answer: $\textsf{(1, 1) is NOT a solution of the inequality}$

-------------------------------------------------------------------------------------------------------------

Given: $y \le-3x + 1$

Find: $\textsf{Determine if (1, 1) is a solution of the inequality}$

Solution: In order to determine if (1, 1) is a solution we need to plug in 1 for the x values and 1 for the y values and see if the equation evaluated to true.
