The table shows the ratio between the number of books ordered and their cost: Number of Books

Cost (dollars)

7

21

8

24

9

27

Find equivalent ratios when the number of books ordered is 1, 2, and 3. Write them as ordered pairs in the form (x-coordinate, y-coordinate). Starting from the origin, explain how to plot the three equivalent ratios on a coordinate grid.

7 14

8 16

9 18

Step-by-step explanation:

The information that is given:

x:  7     8     9

y:  28   32   36

shows us that to find the second value (y), you would multiply the x value by 4.

If the numbers are 1, 2, and 3 the new information would look like this:

x:  1    2    3

y:  4    8    12

The ordered pairs with this information would be:

(1,4), (2,8), and (3,12)

To plot these points, you will begin at the origin (0,0) or the point where the 2 axes/number lines cross).  From here you will move to the right (as far as the 1st number says) on the horizontal number line.  Then you will move up the number of places the 2nd number says.

Always return to the origin before plotting the next ordered pair.

Hope this helps!

Step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
