Rewrite the equation 4x – 10y = 11 as a function of x.
:
4x - 10y = 11
:
-10y = -4x + 11; Subtract 4x from both sides
:
10y = 4x - 11; we want y to be positive, mult equation by -1
:
y = %284%2F10%29x+-+%2811%2F10%29; divide both sides by 10
:
y = %282%2F5%29x+-+%2811%2F10%29
:
f(x) = %282%2F5%29x+-+%2811%2F10%29; f(x) = y
