Question 48126: I was to rewrite the equation as a function of x and this is what I came up with but I cannot figure out which method is right.
2x - 8y = 48
2x + 8y = 2x+48
8y = 2x + 48
8 8 8
y = 2x + 6
8
f(x) = 2x + 6
8

Write:
2x-8y+=+48 as a function of x. What you are really asked to do is to solve the equation for y.
2x-8y+=+48 Add 8y to both sides of the equation.
2x+=+8y%2B48 Now subtract 48 from both sides.
2x-48+=+8y Finally, divide both sides by 8.
x%2F4-6+=+y Or:
f%28x%29+=+x%2F4-6
