Question 800615
The graph of which of the following equations is a straight line parallel to the graph of y=2x?
slope = 2
----------------------- 
A. 4x - y = 4
y = 4x-4
slope = 4
------------------ 
B. 2x -2y = 2
2y = 2x -2
y = x -1
slope = 1
------------------
C. 2x - y = 4
y = 2x - 4
slope = 2
-------------------
D. 2x + y = 2
y = -2x + 2
slope = -2
====================
E. x - 2y = 4
2y = x - 4
y = (1/2)x - 2
slope = 1/2
=============

Note: slope is the amount y increases or decreases when x increases by 1.
