10y%2B4x=20
We need to graph this line.
To do this, we need to isolate for y to get y=mx+b
10y%2B4x-4x=20-4x
10y=20-4x
%2810y%29%2F10=%2820-4x%29%2F10
y=%2820-4x%29%2F10
y=%28-4%2F10%29%2Ax%2B20%2F10
y=%28-2%2F5%29%2Ax%2B2

So we can first plot the y-intercept point (0,2) and then use the slope to get another point (go down 2 and over 5 since slope is rise over run)


This gives us the line:
