Hey man great video, I loved how easy you made all the explinations. Edit: at 15:39 would the answers not be -3+sqrt3 and -3-sqrt3 as it asked for the y co-ordinates, or is your presentation acceptable for an exam board.

Hello there, at 10:35 how did you get 6 as the y coordinate for P? to find the Y coordinate for P, I made x=5 and its was y=5+2 which was 7 instead of 6. I'm not sure if I misunderstood the question or not.

@tonydebling

Y = 4/5 x + 2, when x=5, 4/5 of 5 is 4, plus 2 is 6

L1 has the equation y = 4x/5 + 2. S is the point where L1 crosses the x-axis, therefore y = 0. Substitute y = 0 for y = 4x/5 + 2. 4x/5 = -2. 4x = -10. x = -10/4 = -2.5

haii if you're talking about the IAL Pearson Edexcel one, the P1 (pure mathematics 1) book as well as P2 (pure mathematics 2) are considered AS, and then P3 and P4 for A2/A-levels. They are 4 different books.. 2 for each level with a combination of mechanics (M1) or statistics (S1) but that depends on your school or educational system so ask your teacher to make sure about this

In general, to solve a^x = k, you take log(to the base a) of both sides, which gives x log(base a) a = log(base a)k, as log(base a) a = 1, then x = log(base a) k. In this case you can see what x must be by observation as in earlier comment.

You are told point of intersection of lines has x coord of 5, so subst this into the equation of the line given to find y = 6 so point of intersection is (5, 6). So equation of perpendicular line is (y - 6)=m(x - 5)
