Error using ode45

I have created the following function for my differential equation

function y=opdracht8(x)
y = 0.08x -2000

and i try to solve it with ode45 but matlab gives an error...

[y,t] = ode45(@opdracht8,[0 40], 0);
plot(y,t);

What do i do wrong?

Incorrect number of arguments for the derivative function, and incorrect syntax within that function. E.g.,

function y=opdracht8(t,x)
y = 0.08*x -2000;
