A triangle is to be constructed in the xy-plane such that the x- and y- coordinates of each vertex are integers that satisfy the inequalities -3 ≤ x < 7 and 2 < y ≤ 7. If one of the sides is parallel to the x-axis, how many different triangles with these specifications can be constructed?

10*9*5 for the two points constituting the line parallel to x-axis and 10*4 for the third point within the allowed matrix. Combining for all points gives 18000 as answer. Am I correct? Ans. Plz
