Line WX contains (-1,2) and (4,12).Line YZ contains points (5,8) and (-2,6).Lines WX and YZ are

A)perpendicular,because the slopes are the same

B) parallel, because the product of the slopes is -1

C)perpendicular, because the product of slopes is -1

D) parallel, because the slopes are the same

Slope of line WX = 12-2 / 4+1 = 10/5 = 2

Slope of line YZ = 8-6 / 5 + 2 = 2/7

Slope are neither opposite & reciprocal, nor same. So, They are not perpendicular or parallel.

Hope this helps!
