Here are the equations of 4 straight lines. Two of these lines are parallel what are the two parallel lines? A) y=2x+4. B) 2y=x+4. C) 2x+2y=4. D) 2x-y=4.?

Put ur equations in y = mx + b form and compare the slopes (m) and the y intercepts (b). Parallel lines will have the same slope but different y intercepts.

A) y = 2x + 4 ... slope is 2, y int is 4

B) 2y = x + 4

y = 1/2x + 2 ... slope is 1/2 and y int is 2

C) 2x + 2y = 4

2y = - 2x + 4

y = - x + 2 ... slope is - 1 and y int is 2

D) 2x - y = 4

-y = - 2x + 4

y = 2x - 4 ... slope is 2 and y int is - 4

ur parallel lines will have same slope and different y int ... so ur answer is A and D.
