put this solution on YOUR website!Two nonvertical lines have the same slope if and only if they are parallel.
If you have two nonvertical lines that are parallel, the slopes are the same
From these choices C and D have the same slopes so these two lines are parallel.
A) Y= 5/3x +4 b) y= -3/5x -7 c) y=2x+8 d) y= 2x-4
here is the graph
The red line shows the graph of y=2x+8
The green line shows the graph of y= 2x-4

The red line in this graph show Y= 5/3x
GReen y= -3/5x -7
