Answer 4

there is a useful property pertaining to the slopes of perpendicular lines ... if you know the slope of one line, you can find the perp slope of the other line

Answer 5

that property is: slope1 times slope 2 = -1

Answer 6

the equation will be:

y = (perp slope) x + k

such that k = -2 -(perp slope)(4)

Answer 7

Sorry bout that, I stepped away from my computer to do something. :)

Answer 8

Would the answer be y = -3x + 10? @amistre64
