How to solve the system $2x+4y=8$ and $x+y=1$ by graphing?

Carlee Floyd

The graphical method isn't often used to solve any set of linear equations because it takes a long time, but take a look at it.
$x+y=1$ put any 2 distinct values of x to get 2 distinct values of y .
like the set of values could be
$x=1y=0$
$x=0y=1$
do the same for other equation . plot these values on graph .since these are linear equations the graph would show a straight line .
the point at which the lines intersect is common solution .
