Question

Determine whether the ordered pair (coordinate) is a solution to the inequality.

2. 2x + 3y > -8,
(3,-6)

Answer 1

The ordered pair is not a solution to the inequality.

Explanation:

Given expression;

Inequality :

2x + 3y > -8

Ordered coordinate pair = (3, -6)

Solution:

If the ordered pair is a solution of the inequality, then it must be true that expression on the left -hand side is greater than -8;

So, the values we get on the right-hand side should be -7, -6 on and on.

x = 3 and y = -6

Input the parameters into the inequality;

2(3) + 3(-6)

= 6 - 18

= -12

-12 is less than -8 and this is not correct for the expression.

The ordered pair is not a solution to the inequality.
