**Kuai**, Thursday, October 17, 2013 at 9:38pmy = mx +b

0 = -3/4(4) + b

0 = -3 + b

b = 3

y = -3/4x + 3

**Tracy**, Thursday, October 17, 2013 at 9:57pmThank you. can you explain the steps that you used.

- Correction - Algebra parallel and perpendicular -
**Reiny**, Thursday, October 17, 2013 at 11:41pmKuai is not correct, his line is NOT parallel with the given, since the slopes are different

easiest way:

if the new line is parallel to the given one, it must differ only in the constant

so new equation is

y = (3/4)x + b

sub in (4.0)

0 = (3/4)(4) + b

b = -3

y = (3/4)x - 3
