x= 0 : 0.001 : 20;
y1= 6*sin(t+0.5);
y2= 5;
plot(t,y1,t,y2)
grid
xlabel('x units')
ylabel('y')
getting a error for y1. any help is much appricated

You don't define t in your code. Shouldn't it be x ?
And if you do it this way:
y2 = 5*ones(size(x))
instead of
y2 = 5

Hi Zack
The following code will display the plot as required
x= 0 : 0.001 : 20;
y= 6*sin(x+0.5);
plot(x, y, 'green')
hold on
yline(5, 'red')
grid
xlabel('x units')
ylabel('y units')
hold off
Hope it helps !
