So far I've got:
x = [-100 : 1 : 100];
y = (x - 2) / (2*x + 3);
plot(x,y, 'r')
grid on, axis equal
When I run it, it brings up the plot but the graph is missing.

You forgot the dot (.) operator to do element-wise division:
y = (x - 2) ./ (2*x + 3);
↑ ← DOT GOES HERE!
See Array vs. Matrix Operations for details.

Oh yes, the dot. I was playing with it but left a space between the dot and the / operator. Thanks for the quick help.

My pleasure.
Leaving a space between the dot and the operator will throw an ‘Unexpected MATLAB operator.’ error.

Plot the graph of y = x^2 − 2x − 3.
