Question

Which table represents a linear function?

Answer 1

first one is your answer
x y
1 5
2 10
3 15
4 20
5 25

Answer 2

The table which represents a linear function is:

x y

1 5

2 10

3 15

4 20

5 25

Explanation:

The table of x and y values represent a linear function if for each equal increase in the x-value there is an equal increase/decrease in the y-value.

The table of values is:

x y

1 5

2 10

3 15

4 20

5 25

In this table the x-value is increasing by a constant value 1.

( since,

2-1=1

3-2=1

4-3=1

5-4=1 )

and the y-value is also increasing by a constant value 5.

( since,

10-5=5

15-10=5

20-15=5

and 25-20=5 )
