Which table represents a linear function?

Option 3 is correct.

Step-by-step explanation:

A function is said to be linear if there is same change in x gives same change in y which is also called slope that means if slope for each pair of the given table is same then function is said to be linear.

here in option 3rd we can find the slope for each pair of points its

and its same for each pair of point

therefore  option third is correct

yo answer should be 6 if im not mistaken

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
