The slope of the line through the given points is:
This means the line is horizontal ( zero slope )
------------------
I will say there is a line segment starting at ( 6,3 )
having a slope of
-----------------------------
Also, there is a line segment from ( -2,3 ) having
a slope of
----------------------
These line segments meet at ( x, y ), where
, so the point is ( 2,y )
-----------------------------
I can say:
and
----------------
The third point is ( 2,7 )
The angles of the triangle are 45 -45 - 90
