Answer: see below

Explanation:

QUESTION 6

To find the rate of change, or unit rate, from a table, divide y by x.

64/4= 16

112/7= 16

144/9= 16

208/13= 16

320/20= 16

(a). The rate of change is 16. In other words, Each (1) textbook costs 16 dollars.

(b). The equation is y=16x. This is because to find the cost of any given number of books (x), you just multiply whatever x stands for, by 16. Y stands for the total cost. For instance, in the first row, y=64, and x=4. using the equation y=16x, we can check to make sure 4 textbooks cost 64 dollars.

y=16x

64=16x4

64=64

Correct

QUESTION 7

(a). To find the rate of change from a graph, find the slope. the slope is the same thing as a unit rate, and its formula is Rise÷run.

How to do this?:

First we need to find 2 points. Explained below:

Rise: 50

Run: 2

50/2= 25

Answer=25
