You can create function handles to the named or anonymous functions.

For example, for first equation in your system of equations you can write

x=linspace(-5,5);
f = @(x) (9*x+1)/3;

You can use fplot(f) function to create a plot defined by y=f(x)

fplot(f)
ylim([-5,5]) %to limit y-axis from -5 to 5
