$\"\"$

The derivative of the function is $\"\"$ and the point is $\"\"$ .

Find the function $\"\"$ .

$\"\"$

Apply anti derivative to the function.

$\"\"$ ( since the rate of change of a linear function is constant)

The function passes through the point $\"\"$ .

$\"\"$

Therefore the function is $\"\"$ .

$\"\"$

The function is $\"\"$ .
