Tell whether the line that passes through the two given points is parallel or perpendicular or neither to a line with a slope of -2.
(5,3),(7,-1)
(5,3),(7,-3)
(5,3),(7,4)
==================================
Parallel lines have the same slope
Perpendicular lines have negative reciprocal slope
========================================================
Use the point-slope formula;
Same slope, line is parallel
--------------------------------------
neither
-----------------------------------
Negative reciprocal of -2, so line is perpendicular
