I need help with Question 2 especially and if someone could also guide me the right way about doing question 3, that would help.
I've done Question 2a and got A = (2,0) (If someone could check that would be helpful!!!)
With Question 2b, I tried to make 3y = 2x -12 into y^2 = 4/9x^2 + 16. Is that right? From there I tried factorising but I'm struggling to do it, please help! Thanks!

Your a) is correct.
For b), it's easier to substitute for something that isn't going to be squared. i.e.
2x=12+3y y2=4x−4
Try substituting for x in the second equation. Post your working if you get stuck.
I'm thinking perpendicular lines when they intersect but I dunno how to do that if one line is a curve?
The angle PAQ is made up of three points, P, A and Q. Ignore the curve - this question is about the angle formed by straight lines connecting these points.
If you know the coordinates of these points then you can work out the gradients of the lines.

I have the gradients: A and P = 2 A and Q = 1/2 Q and P = 2/3
What do I do with these gradients? Do I use Pythagoras?
