I found this problem really hard to solve, plz if u know how to do help me out by showing ur working for every single step:-
1) The line p has gradient 2/3 (two thirds) and passes through the point (6, -12). The line q has gradient -1 and passes through the point (5,5). The line p meets the x - axis at A and the line q meets the x-axis at B. Work out the gradient of the line joining the points A and B. (Remember there is only one gradient).
The right answer will get 10 points from me. Thnx a lot guys.

Remember there is only one gradient. Thnx

If A and B are both on x-axis, then the problem has no challenge at all. The gradient = 0.
If B is on y-axis, then
A(24, 0)
B(0, 10)
The slope of AB = 10/(-24) = -5/12

Since point A and B are both on x-axis there is no gradient. Answer is 0.

Points A and B both have y = 0 ( they are x-intercepts of lines p and q ) so the gradient of the line connecting A and B is one.

ok shall we see... prepare that for each non-unfavourable integer n, the selection 7^7^n +a million is the made of a minimum of 2n+3 (no longer inevitably different) top factors. This improve into from the 2007 USAMO. on the competition, I merely wrote for n=0, the difficulty is trivial. something of the info by ability of induction is left as an exercising for the grader. LOL
