An altitude of a triangle is a line drawn from a vertex of the triangle perpendicular to the opposite side of the triangle.Find the equation of the altitude drawn from A(0,0) to the side formed by B(3,4) and C(5,-2).
An altitude of a triangle is a line drawn from a vertex of t
经过B（3,4）和C（5,-2）的直线为：
y=-3x+13
所以垂直该直线的斜率为1/3
过A（0,0）且斜率为1/3的直线为：
y=x/3
即：
x-3y=0
