Question 16460: Rewriting an Equation in Function Form. The certain topic would be rewriting the equation so that y is a function of x, here is the question. 1/4y+3=-5x Now keep in mind that my teacher demands that every evidince of how we solved this is showed please send the work as well if I see and example problem and study off it more thoroughly I might become accustomed to this.
Sincerely,
Jeremiah.

You can put this solution on YOUR website!
Since you want this in the form of y as a function of x, then y is the dependent variable and x is the independent variable.
First, solve your equation for y.
%281%2F4%29y+%2B+3+=+-5x Subtract 3 from both sides.
%281%2F4%29y+=+-5x+-+3 Multiply both sides by the multiplicative inverse of 1/4
y+=+4%28-5x+-+3%29 Simplify.
y+=+-20x+-+12 Now replace y with f(x) since y is a function of x, y = f(x)
f%28x%29+=+-20x+-+12 This is your equation in function form.
