:d triangle abc has vertices a(0,6) b(4,6) c(1,3). sketch a graph of abc and use it to find the orthocenter of abc. then list the steps you took to find the orthocenter, including any necessary points or slope you had to derive.
(i know the exact answer. i know the slopes and the point slope form, but i am basically having trouble with the plotting out the altitudes from the given points. massive brain
