Question

Find the slope of the line through each pair of points.

a)( -7 , 16 ) , ( 4 , - 4 ) b) ( -5 , -20 ) , ( -12 , - 10 )

Answer 1

a) -20/11 b) -10/7

Explanation:

a) m=(y2-y1)/(x2-x1)

m=(-4-16)/(4-(-7))

m=-20/(4+7)

m=-20/11

b) m=(y2-y1)/(x2-x1)

m=(-10-(-20))/(-12-(-5))

m=(-10+20)/(-12+5)

m=10/-7

m=-10/7
