Which best describes the relationship between the lines? 2x - y = - 7 2x + 4y = 2

parallel

neither

perpendicular

same line

perpendicular

Perpendicular

Step-by-step explanation:

2x - y = - 7

2x + 4y = 2

-y = - 2x - 7

4y = - 2x + 2

y = 2x + 7

y = - 1/2x + 1/2

Cannot be:

Parallel because the slope would otherwise be the same.

Same line because the equation is not proportional

So, they are perpendicular because a perpendicular line would be a negative and a reciprocal of the current line
