Explain why you can use a test point to determine which region or regions of the graph of an inequality should be shaded.

We should use a test point to determine the region or regions of the graph of an inequality should be shaded because by plotting an inequality the graph is divided into two regions : one which lie in feasible region and the other does not .

Now in order to check the feasible region we start by taking a test point and see whether it makes the inequality true or not.

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
