Question

Which of the following ordered pairs should be tested to determine which side to shade when graphing the inequality

Answer 1

A

Explanation:

Pick any point on any side of the line. substitute X and Y in the inequality for (x,y)-the point you chose. If you simplify and the inequality is true, shade in that side. If it is false, shade in the other side.

Answer 2

Option A.

Explanation:

If we take an inequality y ≤
`(3)/(2)x-6`, shaded part will be below the line
`y=(3)/(2)x-6`.

But the question is, how to check that the shaded part lies below the line.

To check this we will take two ordered pairs, one above the line and second below the line.

Ordered pair which satisfy this inequality will be in the side of shaded region.

Therefore, Option A. will be the answer.
