Question

Which of the following ordered pairs is not a solution to the inequality y -2x ≤- 3?


(-4, 0)

(-1, 0)

(-2, -1)

(0, -4)

Answer 1

Hint: Substitute the points in one at a time to figure out which is not the solution.

Answer 2

For example: substituting the point (-4,0) would yield:

(0) -2(-4) ≤- 3
8 ≤ -3

8 is not less than -3 therefore, it is not the solution. Try the other points and see what happens
