Question

Which table represents a linear function

Answer 1

Answer:

third table is a linear function

x    y

2    7

4     9

6     11

8      13

Step-by-step explanation:

First table : the value of x are increasing by 2

the value of y is not increasing by a constant. 7+2=9

but 9+3 = 12, so difference in y is not a constant

Second table :the value of x are increasing by 1

the value of y is not increasing by a constant. 7+2=9

but 9+3 = 12, so difference in y is not a constant

Third table: the value of x are increasing by 2

The value of y is increasing by 2 . that is a constant .

Both x  and y have constant increase . So it is a linear function

Fourth table: the value of x are increasing by 1

the value of y is not increasing by a constant. 7+4=11

but 11+1 = 12, so difference in y is not a constant
