**hw**, Tuesday, February 8, 2011 at 8:05pmyou need to get it into slope intercept form--y=mx+b

(m being the slope) to figure out whether they are parallel (having equal slopes) or perpendicular (slopes are negative reciprocals)

2y-x=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
