Question

The inequality 5x - 2y + 1 > 0 is satisfied by point (-2, -1). True False

Answer 1

False

Explanation:

5x - 2y + 1 > 0

plug in the given ordered pair x= -2 and y = -1:-

5(-2) - 2(-1) + 1

= -10 + 2 + 1

= -7 which is less than 0 therefore the answer is False

Answer 2

All you have to do is plug in the coordinates into the problem to see if it is true or false:

5x - 2y + 1 > 0

5(-2) - 2(-1) + 1 > 0

-10 - (-2) + 1 > 0

-8 + 1 > 0

-7 > 0 ... So the answer would be FALSE
