SOLUTION: How do you graph the solution of the linear system: 3x+4y=12 and y=1 and Graph the solution of the linear system: y=0 9x+3y=18 3x+6y=18

Question 182878: How do you graph the solution of the linear system:
3x+4y=12 and
y=1
and
Graph the solution of the linear system:
y=0
9x+3y=18
3x+6y=18

To solve the set graphically, you have to graph both equations.
They're linear, so the graphs are straight lines. 2 points for each eqn are sufficient to fix a straight line.
Find 2 points.
draw a line thru the 2 points.
Do the same for the other eqn
Where they intersect is the solution

you can go to www.padowan.dk.com/graph/ and DL (free) software that will make the graphs for you.
