find the equation for the altitude from each vertex of triangle abc.

• Geometry altitude -

I will do one of them: from A to BC
slope of BC = 10/8 = 5/4
so slope of altitude = -4/5
point on it is (-2,4)
y-4 = (-4/5)(x+2)
5y -20 = -4x - 8

4x + 5y = 12 or y = (-4/5)x + 12/5

do the others the same way
