Below are two different functions, f (x) and g (x). What can be determined about their slopes? f (x) George reads 200 pages in 40 minutes. x g (x) 2 - 8 4 10 6 28

George reads 200 pages in 40 minutes. How many pages does he read in a minute?

m = 200 / 40

m = 20 / 4

m = 5 George reads 5 pages every minute, so the slope is 5.

g (x) passes through (2,-8) and (4,10)

Slope = (10 - (-8)) : (4-2)

Slope = 18 : 2 = 9

The slope of g (x) is 9.
