how to plot the equtaion y=mx+b in matlab

To plot the equation (y=mx+b) in MATLAB, you can follow these steps:

1. Define the values of (m) and (b).
2. Define the range of values for (x).
3. Calculate the corresponding values of (y) using the equation (y=mx+b).
4. Use the plot function to plot the values.

Here is an example MATLAB code that plots the equation (y=2x+1) for (x) ranging from -10 to 10:

main.m
m = 2;  % slope
b = 1;  % y-intercept

x = -10:0.1:10;  % range of x values
y = m*x + b;     % corresponding y values

plot(x, y)
xlabel('x')
ylabel('y')

When you run this code, it will generate a plot showing a straight line with a slope of 2 and a y-intercept of 1. You can modify the values of (m), (b), and the range of (x) to plot different equations.
