1. correct
2. hint: the altitude from B to AC is perpendicular to AC ... what do you remember about slopes of lines that are perpendicular?
3. hint: point-slope form of a linear equation
Here is the question which I am trying to solve:
Triangle ABC has vertices at A (-1,4) B (8,2) C (11,-4)
1.Find the slope of side AC (I think it is -2/3)
2.Find the slope of the altitude from B to side AC
3.Find the equation in slope intercept form of the altitude from B to side AC
Any help would be appreciated. Thank You!

Ok so is #2 then 3/2 since it is the opposite reciprocal? Is #3 then y=3/2x-10/3? If someone could now at this point just give me the answer and how they got it would be appreciated.
