Question

Which function haves the greatest rate of change?

A) y=3x-4

B) 4y-8x=1

C) a line passing through points (2,6) and (3,10)

D) a line passing through points (5,-2) and (6,4)

Answer 1

D

Explanation:

a) rate of change = 3

b) 4y - 8x = 1

y - 2x = 1/4

y = 2x + 1/4

rate of change = 2

c)

{2a + b = 6

{- 3a - b = - 10

- a = - 4

a = 4 (rate of change = 4)

d)

{5a + b = - 2

{- 6a - b = - 4

- a = - 6

a = 6 (rate of change = 6)

6 > 4 > 3 > 2
