MHB Where is Bisector Valley? Uncovering Its Location

[Ilikebugs]

View attachment 6568 Is there a way to determine where Bisector Valley is?

The first leg of Ima's journey lies along the line passing through the origin, with slope -1...so using the point-slope formula can you determine the line.

The second leg of her journey lies along the line passing through the point (0,4) and has a slope of 1...can you determine this line?

Now, find where the two lines intersect to get the coordinates of Bisector Valley. :)

Note: There are simpler ways to determine the answer to this question, but since coordinate geometry was mentioned, I felt it more appropriate to use it to work the problem. :D

The line of the first leg is y=-x
The line of the 2nd leg is y=x+4

-x=x+4

x= -2
y=2

Points= 0,0 -2,2 0,4

2 sqr(2)+2 sqr(2)+4= 4+4 sqr(2) km?

Looks good to me. (Yes)
