You can put this solution on YOUR website!
Both are Line Equations---system%28x-2y=-6%2Cy=-3x%2F2-1%29
It seems you want them to show in the graph.
In the 1st eqn, as we follow Slope-Intercept Form,
2y=x%2B6 --->cross%282%29y%2Fcross%282%29=%28x%2B6%29%2F2
y=%281%2F2%29x%2B%286%2F2%29
Reduced -->y=%281%2F2%29x%2B3, Slope=1%2F2, y-intercept=3
f(y)=0:
%281%2F2%29x=-3 ---->cross%281%2F2%29x%2Fcross%281%2F2%29=-3%2F%281%2F2%29
x=-3%282%2F1%29=-6
.
2nd eqn:
y=-3x%2F2-1 ---> already in the format: Slope=-3%2F2, y-intercept=-1
F(y)=0:
%28-3%2F2%29x=1 ----> cross%28-3%2F2%29x%2Fcross%28-3%2F2%29=1%2F%28-3%2F2%29
x=-2%2F3
As we see below,
---> RED Line >>>> x-2y=-6; GREEN Line>>>>> y=%28-3%2F2%29x-1
Thank you,
