I am reasonably certain that these are correct, but I just want to make sure.

Find the slope and y-intercept of the following:

5x-2y=3

My answer: y=(5/2)x+(3/2)

------------

Indicate which of the following sets of lines are parallel,perpendicular, or neither.

y=2x-5

y=2x+5

My answers(respectively):slope=2,y-intercept=-5

slope=2,y-intercept=5

The lines are parallel.

********************

3x+y=5

-x+3y=6

My answers(respectively):y=-3x+5

y=(1/3)x+2

The lines are neither.

*********************

3x+y=5

x+y=3

My answers(respectively):y=-3x+5

y=-x+3

The lines are neither.

Thank you in advance for you help!
