<PRE><B>Question 196992</B>
Which 2 are parallel when graphed?
a)y=1/3x+5 - y=1/3x-1
b)y=2x-1 - y=-2x+5
c)y=3x+4 - y=1/3x+1
d)y=4x-1 - y=1/4x+3
e)y=x+3 - y=5x+3
--------------------
Check the slopes.  The lines will be parallel if the slopes are equal.
Ans: y = (1/3)x+5 ; y = (1/3)x-1
Both have a slope of (1/3)
