turn this into standard form: y= 4 + 1/5x
standard form is ax + by = c

If the questions is
y = 4 + x/5 (i.e., a fifth of x)
you first multiply everything by 5 to get rid of the deniminator to get
5y = 20 + x
Move the x to left of the equation and you get
-x + 5y = 20
Note: the answer Chris got is the same as mine, to get from his answer to mine, or vise versa, multiply both sides of the equation by -1, it doesn't change the equation since you're doing the same thing to both sides).

multiply the equation y= 4 + 1/5x by 5. then you will get
5y = 20 + x
x - 5y = -20 that is the answer

y = 4 + 1/5x
5y = 5(4) + 5(1/5x)
5y = 20 + x
- x + 5y = 20 + x - x
-x + 5y = 20
-x + 5y = 20 is in standard form.

multiplying by 5
5y=20+x
x-5y+20=0
