re-write each equation in the slope-intercept form:
y=mx+b [solve for the y-term]
.
3x - 6y = 9 [solve for the y-term]
-6y=-3x+9
-6y/-6=-3x/-6+9/-6
y=1/2x-3/2 [graph this equation of a line}
.
x - 2y = 3 [solve for the y-term]
-2y=-x+3
-2y/-2=-x/-2+3/-2
y=1/2x-3/2 [graph this equation of a line]
.
Notice that since the equations are the same, they will be the same line.
