College Placement Test
The graph of which of the following equations is a
straight line parallel to the graph of y = 2x ?
A. 4x – y = 4
B. 2x – 2y = 2
C. 2x – y = 4
D. 2x + y = 2
E. x – 2y = 4
C. 2x – y = 4
Recognize that y = 2x is y = 2x + 0,
Explanation:
which is y = mx + b form of a line.
The slope is 2 and the y-intercept is 0
Recall that parallel lines have equal slopes
Solve each answer for y
(y = mx + b form)
A. y 4x - 4
B. y x - 1
C. y 2x - 4
