Answer:
Equation c represent the table .
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 .
