To bring the equation 5x + 4y = 0 to the form of a linear function y = kx + m, we first move all y to the right side of the equation, and all x to the left:
5x + 4y = 0;
4y = – 5x.
We divide both sides of the equation by the coefficient pr y (4):
y = – 5x / 4;
y = (- 5/4) * x is a linear function, where k = – 5/4, m = 0.
