I have no clue how to do this

Y=1x+0

Step-by-step explanation:

Simple y1-y2 over x1-x2 so...

2-(-2)=4

2-(-2)=4

So Slope of 1 then you pick any coordinate on the line and sub in the y. So I choose (0,0) cuz ya know easy.

SO...

Y=1x+0

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
