Can you me out with this question i really need it you❤️

There is a line with slope 1/a going through the point (a, a²). find the equation of the line perpendicular to this line at this point. (don’t let this problem intimidate you! solve the problem as you would if i’d given you specific values. just use variables instead.)

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?
