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

Explanation:
To find the value of x by using completing the square, first, we need to subtract 59 on both sides of the given equation:
So,
From the given equation:
Now,
Take half of the x term and square it:
So,
From the x term,
Then,
Add 64 on both sides of the above equation.
So,
