I have a test today and i'm not sure how to do somethings

Draw each pair of graphs on the same axes. In each case, tell what is the same and what is differnt about the graphs.

1. y= 1 over 4x; y= -1 over 4x

2. y = 4x; y= 4x - 2

Use the intercepts to graph each equation.

3. 2x - y = -4

thankyou however helps!!
