What is the inequality for the graph?
I just need someone to check to see if my answer is right.

\[y \ge -x+6\] or
\[y \ge-\left| x-5 \right|+1\]

It's obviously not the first option..otherwise the outline would be a straight line.

You only have 2 choices..don't you?

Well the second one looks incorrect also..

I don't have any answer choices to pick from, so I have to create an equality

OpenStudy (igreen):
Oh, okay.

Can you help me figure out the equality?

Is the line dotted or solid..?

OpenStudy (igreen):
It looks solid to me.

Yeah, it's a solid line

Okay, the inequality is going to be:
\(y \ge |x - 5| + 1\)

Just copy and paste it into a box on the left.

I just experimented with the graph..

Well subtracting the x in the brackets shifts it to the right, and adding it shifts it to the left. Adding outside of the bracket makes it go up, and subtracting outside of the bracket makes it go down.

OpenStudy (igreen):
Therefore, you subtract x in the bracket by 5, and you add outside of the bracket by 1.

Ok. So, what about the y-intercept? y=6

OpenStudy (igreen):
Yeah, the y-intercept is 6.

So I just leave it out of the inequality?
