Answer:
Bottom right table
Explanation:
A table will show a linear relationship when there is a common difference. To determine this, we first ensure that the x values are increasing at the same value and then find the difference of consecutive y values.
Top left table
11-7=3
12-11=1
13-12=1
Because the differences between the y values are not all the same, this table does not represent a linear function.
Top right table
9-7=2
12-9=3
15-12=3
Again, there is no common difference, so this table does not represent a linear function.
Bottom left table
The x values are different now but they still increase by the same increment each time, so we continue subtracting the y values normally.
9-7=2
12-9=3
15-12=3
This table does not represent a linear function.
Bottom right table
9-7=2
11-9=2
13-11=2
Because there is a common difference, this table represents a linear function.
I hope this helps!
