y=3/4x-1 write equation for a line parallel to the given line passing through (4,0)
Algebra parallel and perpendicular - Kuai, Thursday, October 17, 2013 at 9:38pm
y = mx +b
0 = -3/4(4) + b
0 = -3 + b
b = 3
y = -3/4x + 3

Kuai is not correct, his line is NOT parallel with the given, since the slopes are different
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
