Triangular grid in cartesian plane!

Find the number of ways to from (0,0) to (8,8) in the right angled isosceles triangle forming the sides:

1) (0,0) to (8,0)

2) (8,0) to (8,8)

3) (0,0) to (8,8)

You can only go in positive vertical or horizontal directions(only integer co-ordinates). Diagonals are not allowed.

Bonus: Try to find the number of ways for a general case like (0,0) to (m,m)
