Rewrite the equation 4x – 10y = 11 as a function of x.
:
4x - 10y = 11
:
-10y = -4x + 11; subtracted 4x from both sides:
:
10y = 4x - 11; we want y to be positive, multiplied equation by -1
:
y = 4%2F10x - 11%2F10; divide equation by 10 to give y a coefficient of 1
Could also write it
y = .4x - 1.1
:
usually f(x) = y
therefore
f(x) = .4x - 1.1
