Question 28439: Solve the system by graphing.
3x + y = 6
3x – y = 0

You can put this solution on YOUR website!
You need to first put this in slope-intercept form;
3x+y=6
y=-3x+6
3x-y=0
-y=-3x+0
y=3x-0
Now you need to plot the pionts on a graph;
For equation 1 your y-intercept is going to be 6;
So from the point (0,6), move 3 units down and 1 unit to the right, then plot that point and connect to points with a line.
For equation 2 your y-intercept is 0;
So from the point (0,0)(origin), move 3 units up and 1 unit to the right, connect those points with a line.
