OpenStudy (mhchen):

First of all, the questions says choose a random point in the shaded region. Pick a random point and post it. We'll work with that.

OpenStudy (campayne):

oh god that makes zero sense

OpenStudy (taylor0402):

ummm im trying to figure out a way to word this for you give me a second

OpenStudy (shadowlegendx):

A random point, or random coordinate, is like (0,1) or (3,2)

OpenStudy (shadowlegendx):

What do you not understand?

OpenStudy (campayne):

like.. i dont know it makes not in the least sense none of it.

OpenStudy (shadowlegendx):

This, y ≥ -x - 1 is the inequality

OpenStudy (shadowlegendx):

We want to use any random point in the shaded region of the graph, and test it in inequality

OpenStudy (shadowlegendx):

The easiest point to test, would be (-1, -1), which lies in the shaded region.

OpenStudy (shadowlegendx):

Input (-1, -1) into y ≥ -x - 1 \[-1 ≥ -(-1) - 1 \] Simplify \[-1 ≥ 1 - 1 \] Simplify \[-1 ≥ 0\] Is this true?

OpenStudy (campayne):

i suppose, when you put it like that, right?
