Annoying Math Problem

[FZE]

I've been posed with this question:

So far, I have made these calculations:

I'm confused by the results here and I'm not really sure how to go about proving that lines MQ and MR are the solutions to that particular problem. I got the z= figures on the right from Wolfram Alpha, but the trouble is using my calculations to reach those conclusions.

Any assistance here?

Just tell the teacher that you'll never EVER use that in normal life and thus didn't do it, since it was a waste of time.

That's not necessarily true among engineers.

You're out of your vector, so zetta slow!

I don’t think much people from Facepunch play TWEWY.

I hate when people say that, my dad uses these kinds of equations every day so how the hell can you say you don't use that in normal life?
