The table shows a proportional relationship between the weight on a spring scale and the distance the spring has stretched. a. Complete the table.

b. Describe the scales you could use on the x and y axes of a coordinate grid that would show all the distances and weights in the table.

distance (cm) weight (newtons)
20 28
55
140
1

55= 39 2/7

Step-by-step explanation:

See below

Step-by-step explanation:

As per the first row of proportional relationship, the proportion is:

The function is therefore:

a) Table is filled in below:

distance (cm)             |         weight (newtons)

20                               |         28

55                               |         55*1.4 = 77

140/1.4 = 100              |          140

1                                  |           1*1.4 = 1.4

b)  The scale should consider the coefficient 1.4, therefore x- axis will have a scale of 100 with intervals of 1 cm and y- axis will have a scale of 140 with intervals of 1.4 newtons
