right triangle abc is to be drawn in the xy - plane so that the right angle is at a and ab is parallel to the y - axis . if the x - and y - coordinates of a , b , and c are to be integers that are consistent with the inequalities - 8 ≤ x ≤ 2 and 4 ≤ y ≤ 9 , then how many different triangles can be drawn that will meet these conditions ?
n0 = 8.0
n1 = 2.0
n2 = 4.0
n3 = 9.0
t0 = n0 * n3
t1 = n0 - 1.0
t2 = n0 * t1
answer = t2 * t0
