How do I plot a linear equation y=mx+b?
So let's say I have this:
b0= 3 where b0 is the y-intercept b1= 4 where b1 is the x coefficient
Then:
Y= b0-b1*X
How do I plot this?

Or:
By all means, the solution method above will work. However, as your function increases in complexity, that command becomes more and more expensive. Try defining your domain x, then, as a vector:
MATLAB code
b0=3; b1=4;
x= linspace(xmin,xmax, n); % Adapt n for resolution of graph
y= b0-b1*x;
plot(x,y)

xmin, xmax, and n are things you can change in the code for various views of the graph

bo = 3;
b1 = 4;
% You can choose any range of x. In this case I chose x is from -50 to +50
x = -50:50;
plot(x,y)
