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;
For more information about creating function handles refer to the link https://www.mathworks.com/help/matlab/matlab_prog/creating-a-function-handle.html
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
For more information about fplot refer to the link https://www.mathworks.com/help/matlab/ref/fplot.html
