Answer by kkasko(46)   (Show Source):
You can put this solution on YOUR website! y = x -4
y = 3x
solve each system of equations by graphing
This question can be solved both with or without a calculator.
If solving with a calculator
Press Y= with the graphing calculator and enter x-4 into y1
and 3x into y2
Then press graph
Then 2nd calc intersect
Enter, enter, enter
X=-2 Y=-6
(-2,-6)
If graphing by hand
Draw a x and a y axis
Draw a dot on (0,-4) which is on the y axis go up 1 and right one as far as possible. Then do the opposite on the - side. Go down one left 1.
Draw another dot on (0,0) go up 3 and right 1 as far as possible . Then do the opposite on the - side go down 3 and left one. The points should connect and that is the intersection. It should be (-2,-6) if it has been done properly.
