Write an equation for the line that is parallel to the given line and passes through the given point.

y=3x+4;(6,8)
A. y=3x-10
B. y=3x+6
C. y=-3x+6
D. y=-1/3x-6

Tell whether the lines for each pair of equations are parallel, perpendicular, or neither.
y=-3x+7
-2x+6y=3
A. Parallel
B. Perpendicular
C. Neither

1. B
2.A
Thank you for the help

To check #1
You say B which is y=3x+6
if x = 6
y = 3(6) + 6 = 18+6 = 24
NO!
See, you can check without asking me.


y = 18+b
y = 8
8 = 18+b
b = -10
so the RIGHT answer is
y = 3x -10
which is A


now
slope of first = -3
second is
6y = 2x + 3 , slope = +1/3
second slope = -1/first slope
so
PERPENDICULAR
