Part 2: Describe the graph of the solution.

queelius · Answer

Solve by solving this inequality in terms of y, i.e., try to make it where y is on one side of the inequality, and everything else is on the other side.

What will be the answer @queelius  ????

queelius · Answer

I'll start it.

-2y - 7 > 11
-2y > 18

What's next?

goformit100 · Answer

y < -9

queelius · Answer

Yup. So, what does that look like on a graph?

goformit100 · Answer

Don't know.

queelius · Answer

We'll assume we're talking about a 2-dimensional graph, where y is up and down and x is left and right.

queelius · Answer

So, every point on that graph that *satisfies* that inequality, y < -9, must have it so that the y component is less than -9, and the x component can be anything.

queelius · Answer

Any ideas?

No.

Everything below the dashed line, which is at y = -9, is a point that satisfies the inequality y < -9.
