Homework Help: math

Posted by Emil on Wednesday, November 23, 2011 at 2:09pm.

I have a triangle in a coordinate system(not native english) i have these three points.
A: 4,-2
C: 4,3
How do i get the height of it in relation BC?
And, how do i calculate the total area of the triangle?

Made this atm:

((-2)-4)/((-1)-2) = 2;
y = 2*x;
(4+2)/(3+1) = 3/2;
y-2 = 3/2*(x-1);
y = (3/2)*x+1/2;

Took explanation out, it is in another language ;)
