Graph
-x + 3y = -9 by graphing the x and y intercepts. 
Let x=0 and solve for y, this is the y-intercept:
-(0)+3y=-9
3y=-9
3y/3=-9/3
y=-3
Plot (0,-3)
:
Now let y=0 and solve for x, this is the x-intercept:
-x+3(0)=-9
-x=-9
-(-x)=-(-9)
x=9
Plot (9,0)
Connect the points and you have a line that looks like:
{{{graph(300,200,-10,10,-10,10,(x-9)/3)}}}
Happy Calculating!!!</PRE>
