# Help, write an equation...?

Write an equation in standard form for a line that is (a) parallel (b) perpendicular to the line with an equation of 5 3 − = x y that passes through the point (8, 5).

Update:

i wrote the equation wrong, it's y=3x-5

y = 3x - 5

There is no general agreement on the meaning of standard form. This is what I would call standard form for that same line:

3x - y = 5

The parallel line through (8, 5):

3x - y = 3(8) - (5)

3x - y = 19

The parallel line through (8, 5):

x + 3y = (8) + 3(5)

x + 3y = 23

You'll need to clean up the equation. I can tell you that a parallel line shares the same slope as the original line, and for a perpendicular one, you flip the slope.
