Question

Which is largest?

A: The slope between (0,0) and (-3,8)
B: the slope between (-1,7) and (8,-2)
C: the slope between (5,7) and (-1,3)
D: the slope between (-3,-5) and (3,-15)

Answer 1

A: m = -8/3 = -2 2/3

B: m = (-2 - 7)/(8 - (-1)) = -9/9 = -1

C: m = (3 - 7)/(-1 - 5) = -10/6 = -5/3 = -1 2/3

D: m = (-15 - (-5))/(3 - (-3)) = -10/6 = -5/3

= -1 2/3

Line A has the largest slope.
