Question

What is the rate of change for the function represented

Answer 1

Answer:

$1.50 per book

Step-by-step explanation:

m = (y2 - y1)/(x2-x1)

substitute given values

m= (275 - 50)/(250 - 100)

m = (225/150)

225/150x = 3/2x = 1.50x

Now

substitute values and find y-intercept

y = mx + b

f(x) = 1.50x - 100 or y = 3/2x + (-100)
