1)Find an eauation of the line containing the given pair of points.
(2,1) and (6,3)
MY ANSWEAR: Y=(1/2)X
2)Decide whether the pair of lines is perpendicular, parallel, or neither.
--What is the slope of
4x+2y=3
4x+2y=4
MY ANSWEAR: (1/2) AND -2 (PERPENDICULAR)
#1 yes
#2, no
4x+2y=3
4x+2y=4 both have a slope of -2, so they are two parallel lines.
