I need toIs the following pair of lines parallel or perpendicular? Prove your answer.
2y – x = 2
y + 2x = 4
can you explain how to break this down ...

you need to get it into slope intercept formy=mx+b
(m being the slope) to figure out whether they are parallel (having equal slopes) or perpendicular (slopes are negative reciprocals)
2yx=2
2y=x+2
y=1/2x+1
slope=1/2
y+2x=4
y=2x+4
slope=2
2 and 1/2 are negative reciprocals making these two line perpendicular 
Thank you I did not see the answer. Thank you so much
