Question

Is the point (-3, 2) a solution of x - 5y < 7? Explain how you know.

Answer 1

yes

Explanation:

Substitute x = - 3 and y = 2 into the left side of the inequality and compare the value obtained with the right side.

- 3 - 5(2) = - 3 - 10 = - 13 < 7

Thus (- 3, 2) is a solution of the inequality
