Question

Ben joins a book club. He pays $12 for each book and $5 for shipping and handling charges for each order.

Answer 1

`y=12x+5`

The graph in the attached figure

Explanation:

The question is

Write an equation and make a graph that represents the total cost

Let

x ----> the number of books

y ---> the total cost in dollars

we know that

The linear equation in slope intercept form is equal to

`y=mx+b`

In this problem we have

The slope or unit rate is equal to

`m=\$12\ per\ book`

The y-intercept is the fee for shipping and handling charges

`b=\$5`

substitute

`y=12x+5`

To graph the line we need minimum two points

we have the y-intercept (0,5)

Find another point

For x=2

`y=12(2)+5=29`

The other point is (2,29)

Plot the points, connect them and join to graph the line

The graph in the attached figure

Remember that the value of x and the value of y cannot be a negative number
