y = 3-5x/20
Jace, seriously, that was horrible man.
5x + 20y = 60
Substract 5x from both sides.
20y = 60 - 5x
Divide by 20 to isolate y.
y = 3 - 5/20 x
Simplify the fraction.
y= 3 - 1/4 x
Put into standard form.
y = - 1/4 x + 3
Remember that y=mx+b, m equals slope, and b equals y-intercept.
Thus, slope equals -1/4, and y-intercept equals 3.
5x + 20y = 60
Substract 5x from both sides.
20y = 60 - 5x
Divide by 20 to isolate y.
y = 3 - 5/20 x
