Substitute the values of the coordinates of the given point for and in the given inequality. Do all indicated arithmetic. If the result is a true statement, then the point is an element of the solution set of the inequality; otherwise, not.

3x - 15y ≥ 10

3(2) - 15(-6) ≥ 10 ... plug in x = 2 and y = -6

6 + 90 ≥ 10

96 ≥ 10

This is true, so (2,-6) is indeed a solution.
