You can put this solution on YOUR website!
In order to type it into your graphing calculator, you usually have to solve the equation for y.
4x%2B5y=80subtract 4x from both sides:
5y=-4x%2B80divide by 5.
y=-4x%2F5%2B16
Now you can key y=-4x/5+16 into you graphing calculator and get:
graph%28300%2C400%2C-5%2C+25%2C+-5%2C+20%2C%0D%0A-4x%2F5%2B16%0D%0A%29
