Answer:

Explanation:

let the number of copies she sells = x

let her total pay = $y

the relation between x and y is described the equation,

y = 90x + 2300

a)

change in Christine's total pay for each copy of math is fun she sells:

change will be 90 times number of copies she sells and then added to the constant 2300

b)

if number of copies she sells, x = 0

Christine's total pay, y = 90(0) + 2300

= 0 + 2300

= $2300
