Question

Coordinate Geometry: Find the coordinates of the orthocenter of (triangle symbol)ABC with vertices A(-3, 3), B(-1, 7), and C(3,3). Please help and show work (:!

Answer 1

Break out the graphing paper

Answer 2

Can you help me?

Answer 3

Alright get the general procedure
do as directed keep replying

Answer 4

Find slope of any one side

Answer 5

Ok, So how would I do that?

Answer 6

It's better to start with AB: A(-3, 3), B(-1, 7)
Do you know slope formula from 2 points?

Answer 7

y2-y1 and x2 - x1?

Answer 8

Yep, show us your work by plug the coordinate in, will you!

Answer 9

m = (y2-y1)/ ( x2 - x1)

Answer 10

Ok, I get how to do it now

Answer 11

then find the equation of AB:

Answer 12

y - yA = m ( x - XA)

Answer 13

That's the formula?

Answer 14

Don'i find AB
You know slope of AB find slope of line perpendicular as altitude through C is perpendicular to AB find the equation of altitude through C

Answer 15

Don't we need the intersection point between these segments?

Answer 16

No

Answer 17

Have you find out slope of AB yet?

Answer 18

you have the altitudes
