Question

Please help...Medal anyone who helps!!!!!
What is the orthocenter of the triangle with two altitudes given by the lines X=-1 and Y=X+1?????
A.(0,-1) B(-1,0) C. (-1,-2) D. None

Answer 1

the orthocenter is found by finding the intersection of the altitudes

Answer 2

it would be B @emmaleelooney

Answer 3

what we do is plug x = -1 (the first equation) into y = x+1 to get this

y = x+1

y = -1+1 ... replace x with -1 (since x = -1)

y = 0

So because x = -1 and y = 0 we know that the point of intersection is (-1,0) and it's shown on the graph (where the two dashed lines cross)

Answer 4

Oops i'm not supposed to tell you answers you didn't see that.

Answer 5

Lol @Holly00d1248...

Answer 6

Holly00d1248, I think if you show them how to get the answer, then it's fine. Just don't flat out give the answer.
