EZ Math Movie, Tutorials, Simple Graphics, Drawing a Line Segment


Drawing a line segment

Here we will learn how to draw a line segment between two points. We will call the first point (x1, y1), and we will call the second point (x2, y2). Our new command:

drawLineSegment(x1, y1, x2, y2);

The following line of code would draw a line segment from point (3, 5) to point (6, 8):

drawLineSegment(3, 5, 6, 8);

We will use setupGraph, which sets the line thickness to 2 and it's color to black.

Line segment coordinates

Here is a picture that shows how the drawLineSegment command states the endpoint coordinates.

Line segment coordinates, (x1, y1) and (x2, y2)

drawLineSegment(-5, -3, 6, 4);

drawLineSegment(-5, -3, 6, 4)

Running the example program

Our example program shows how to use the drawLineSegment command to create a simple design.
