Which table represents a linear function ?

Table 3 from the left.

Step-by-step explanation:

In the tables attached, we have to find a table which represents the linear function.

The values of y are changing with the different values of x.

If the values of y have a common difference in each successive term of the table then the function formed will be linear.

For 3rd table from the left,

At x = 1 and x = 2,

Difference in y values = -5 - (-3)

= -5 + 3

= -2

At x = 2 and x = 3,

Difference in y values = -7 - (-5)

= - 7 + 5

= -2

Similarly all successive values of y has a common difference of (-2).

Therefore, table 3 from the left represents a linear function.

Step-by-step explanation:

From the question we are told that:

Total amount spent

Rate

Generally the equation for Total pound of coffee W is mathematically given by

Total pound of coffee=Total amount spent/Rate
