How do I solve this??
I tried something but I'm lost
However, since the questions asks for the y coordinate a better approach would be to rearrange the given line equations into the form x = (something) then equate the two expressions. That way you avoid having to find x first then y second.
In other words, you need to simplify into a single quotient and then you will be able to choose the right answer.
