D
=
number of dollars
p
=
number of pounds

drag each table and equation to the unit rate it matches.

General equation of line :   --1

Where m is the slope or unit rate

Table 1)

p    d

1      3

2     6

4     12

d = Number of dollars (i.e.y axis)

p = number of pound(i.e. x axis)

First find the slope

First calculate the slope of given points

  ---A

Substitute values in A

Thus the unit rate is 3 dollars per pound.

So, It matches the box 1 (Refer the attached figure)

Equation 1 :

Since p is the x coordinate and d is the y coordinate

On Comparing with 1

Thus the unit rate is dollars per pound

So, It matches the box 2 (Refer the attached figure)

Equation 2 :

Since p is the x coordinate and d is the y coordinate

On Comparing with 1

Thus the unit rate is 9 dollars per pound

So, It matches the box 3 (Refer the attached figure)

Table 2)

p        d

1/9      1

1         9

2        18

d = Number of dollars (i.e.y axis)

p = number of pound(i.e. x axis)

Substitute values in A

Thus the unit rate is 9 dollars per pound

So, It matches the box 3 (Refer the attached figure)

555.99.
