my ans shld be correct but for part c i used equations of lines and perpendicular gradient (m1m2 = -1) to solve which might be a longer step? and not sure if you have learned it yet. If it involves concept you have yet to learn maybe you can wait for an alternative solution? XP

If the student is not taking Additional Mathematics, your method used in (c) could be difficult for her to comprehend eh [the subject quoted was E Math]. Likewise for (b), she might not know Surds.

For information eh, thanks. :)
