OpenStudy (anonymous):

can you help?

OpenStudy (aum):

Find the intersection of the two altitudes and that will be the orthocenter.

OpenStudy (mathstudent55):

What is the definition of the orthocenter of a triangle?

OpenStudy (anonymous):

@aum I couldn't have said it any better myself

OpenStudy (anonymous):

three altitudes intersect in a single point, called the orthocenter of the triangle. The orthocenter lies inside the triangle if and only if the triangle is acute

OpenStudy (aum):

You can read the point of intersection off the graph or you can solve for it from the two equations.

OpenStudy (mathstudent55):

Good. All altitudes intersect at the same point. You have two altitudes drawn and shown intersecting at a point. That point must be the orthocenter. Just read the point.

OpenStudy (anonymous):

0,-1 ?

OpenStudy (aum):

you have switched the x and y.

OpenStudy (anonymous):

so -1,0?

OpenStudy (aum):

Yes. But put a parenthesis around it.

OpenStudy (anonymous):

Thank you!!
