Which equation represents the data shown in the table below

Equation c represent the table .

Step-by-step explanation:

Given : Table of data cost(x) : 2   4    6   8

                               Gallon (y) :5   10  15  20.

To find: which equation represents the data shown in the table.

Solution : We have given

 cost(x) : 2   4    6   8

Gallon (y) :5   10  15  20.

Equation C

y = 2.5 x

For x =2

y = 2.5 ( 2).

y = 5.

For x = 4.

y = 2.5( 4).

y = 10.

For x = 6

y = 2.5 (6).

y = 15.

For x =8

y = 2.5 ( 8)

y = 20.

Therefore, Equation c represent the table .
