Question

Determine if the lines that pass through the given points are parallel, perpendicular or neither.
Line A: (-8, 8) and (-5, 10) Line B: (-7, 12) and (-5, 15)
	A.	Parallel
	B.	Perpendicular
	C.	Neither
	D.	Cannot be determined

welshfella · Answer

first  find the equations of the lines:-
the slope of a line is (y2-y1) / (x2 - x1)   where (x1,x2) and (y1,y2)  are the 2 points

welshfella · Answer

so the slope of the first line is (10-8) / (-5 - (-8))

can you work that out?
