Question

Which equation represents a line parallel to 2x+y=-2?

A. y=-2x+3
B. x+y=5
C. y-x=-1
D. y-2x=3

Answer 1

Option A

Explanation:
To find the answer we need to graph the following equations to see which equation is parallel to the given equation 2x + y = -2x. Your answer is option A or "y = -2x + 3." One of the biggest rules when trying to find out if the two lines are parallel to each other is seeing if the two lines intercept. In this case if you graph all the following options, the only line that does not intercept the first line 2x + y = -2 is the option A, which means it's your answer.

Hope this helps.
