How do I plot the plot a line using slope and one (x,y) coordinate on Matlab?

I have the slope, starting coordinates (x1,y1) and distance. Using this I need to plot a line from the known (x1,y1) coordinate. How do I do this?

Let's define the slope as m; So using the equation: y = m(x-x1) + y1, we can calculate all values of y corresponding to a particular x value. Remember Matlab plot graphs by mapping point and connecting the dots. In Code we will do this.

Define the values of x for which we want to plot the graph.

x = -15:0.25:25; % Defines the domain as [-15,25] with a refinement of 0.25

Initialize m, x1,y1;

m  = 2;  % Specify your slope
x1 = -15; % Specify your starting x
y1 = -7;  % Specify your starting y

Calculate the corresponding y-values:

y = m*(x - x1) + y1;

Plot y vs x:

hPlot = plot(x,y); % plot the graph, and store line reference in a variable.
