### Math questions regarding lines and graphs?

Okay. So I have 2 questions to do.

1) Find the equation of a line that passes through the point (2,-5) and is PARALLEL to the line y = 3/4x + 1

2) Find the equation of a line that passes through the point (2, -5) and is perpendicular to the line y = 3/4x + 1.

I'd also like details on how you found the answer. The more detailed, the better!
