Answer: A
Step-by-step explanation:
[tex]4x+4y=20[/tex]
We need to get this form: [tex]y=mx+b[/tex]
we need to begin by isolating y on the left side. To do this, we must subtract 4x.
[tex]4y=20-4x[/tex]
Rewrite it so that we get this form: [tex]y=mx+b[/tex]
[tex]4y=-4x+20[/tex]
Since y needs to be completely isolated, divide by 4.
[tex]y=-\frac{4x}{4} +\frac{20}{5}[/tex]
Divide;
[tex]y=-x+5[/tex]
