Question

Which point is NOT part of the solution of the inequality ?

A. (0, 0)
B. (4, –4)
C. (–3, 2)
D. (–1, 1)

Answer 1

C–I'm 98% sure because it's the only one that look irregular

Answer 2

Well, that is y ≥ -(x-4)-3 or y ≥ -(-(x-4))-3.

So the y-intercepts are 1 and -7.

The slope is + or - 1 because x doesn't have a coefficient.

So everything on or above one of these lines belong. Whatever is below both of them does not.

Our options are A) the origin (0,0)
B) (4,-4)
C) (-3,2)
and D) (-1,1)

Let's start with the origin.

(0,0) is above the line on the left, so it belongs.

(-3,2) is above, too.

And so is (-1,1).

That leaves B) (4,-4) under the lines. Therefore, B is the answer.

You may now pay me... kidding.
