Perpendicular to the line y=1/3x + 6; containing the point (2,-2) You know the line is perpendicular to y=1/3x+6 so we can find its gradient . using the formula , we find that its gradient is -3. This line passes through point (2,-2) Using this formula , Substitute appropriately , we get and simplify it ,
