Answer:

1. $120

2. $2200

Explanation:

The linear function representing Eric' s to total pay is

2200 + 120x = y

By rearranging it, it becomes

y = 120x + 2200

where

y represents the total pay

x represents the number of copies sold

Recall, the slope intercept equation is expressed as

y = mx + c

where

m represents slope or rate of change

c represents y intercept or the value of y when x = 0

By comparing both equations,

rate of change = 120

If he doesn't sell any fun book, x = 0. y = 120 * 0 + 2200. Thus

y intercept = 2200

Thus, we have

The change in Eric's total pay for each Math fun book he sells is $120

Eric's total pay if he doesn't sell any math fun book is $2200
