Parallel lines that pass through points

[Guest]

L1 and L2 are parallel lines. The equation of L1 is y = 3x + 2 L2 passes through the point (3, 4). Find an equation for L2.

L2..... 4 = 3 x 3 + c
c = -5
L2.... y = 3x - 5

L1 is y = 3x + 2
L2 =?
L2 pases through point (3,4)
x= 3 and y= 4

4= 3x3 + c
4= 9 + c
c= -5

so the L2 is y= 3x - 5

nice post

[HallsofIvy]

Yes, they were both nice posts. But I would NOT recommend useing "x" to indicate multiplication (as in "3x3") when it is already being used to represent a variable. Better would be 3*3 or 3(3).
