Determine point 1
Let
So

Determine point 2
Let
Add 3 to both sides
But -3+3=0#
So
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Determine checking point 3
I chose an
So
'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Mark the points and draw a straight line through extending it to the edge of the squared area on the paper.
