Question

Find the orthocenter of the triangle with vertices (-10, 11), (8, 2), and (2, -1).

Answer 1

the orthocenter is the intersection of the altitudes you have to plot the triangle
draw the altitudes to find the intersection
I get (1,-11)but you would be better to check or you won't learn how easy it is to
make mistakes

Answer 2

as I said it,s easy to make a mistakeI I now say intersection is(-1/4,-13/4)
especially when point is outside the triangle
