Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
:
by the graph one can see that the solution is (1,-1)
:
plugging this value into each equation verifies this solution
:
systems with one solution are consistent and independent systems
:
if your looking for how to graph......simply choose a value for x and solve for y..
example y=3x-4 for x=1 y=3(1)-4=-1.
:
you only need 2 points plotted to draw the line...but a 3rd point is good for making sure you havent made a mistake
