You can put this solution on YOUR website! y=3x-7
y-2x=-6
Solve each sysem by graphing
-------
y = 3x-7
y = 2x-6
----
Rather then guessing, solve by substitution to get x = 1
and y = -4
------
Then plot a few points around x = 1 to get the shape of
the 2 lines.
!st equation points: -2,-13 ; 0,-7 ; 1,-4 ; 3,2
2nd equation points: -2,-10 ; 0,-6 ; 1,-4 ; 3,0
----
Plot those poinse and draw the 2 lines.
---------
Cheers,
