You can put this solution on YOUR website!
THE FIRST POINT IS (0,-3) THE YINTERCEPT.
SETTING Y=0 & SOLVING FOR X WE GET:
0=X-3
X=3 OR (3,0) FOR THE X INTERCEPT.
NOW SET X TO ANY NUMBER & SOLVE FOR Y THUS:
Y=6-3
Y=3 OR(6,3) IS THE THIRD POINT..
WHEN PLOTED YOU HAVE:
+graph%28+300%2C+200%2C+-6%2C+7%2C+-10%2C+10%2C+y+=+x+-3%29+ (graph 300x200 pixels, x from -6 to 7, y from -10 to 10, y = x -3).
