That would give 2x−4y=02x-4y=0

I'll give you a clue, it involves addition

Exactly, so what would you do to make -2y become 2y?

Yep!

So, now we have: x=2yx=2y

How would you get the y on its own?

Correct, so now it's y=x2y=\frac{x}{2}

What would you do next?

Maybe if I wrote it a different way.... y=12x+0y=\frac{1}{2}x+0

Does that make it easier?

so m= 1/2, and then you plug that into m=tan theta?

is the answer 26.6 degrees?
