Question

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

 

is it perpendicular because the product of the slopes is -1?

Answer 1

The slope of WX is m_WX = (12-2)/(4-(-1)) = 10/5 = 2

 

The slope of YZ is m_YZ = (-6-8)/(-2-5) = (-14)/(-7) = 2

 

The two lines, WX and YZ, have the same slope, so they are parallel.
