Geogebra – Coordinate Geometry – straight line equations

** To explore about the distance of a line segment (length of an interval between two points), click on the link below:

*** Change the position of the points A and B, make the right-angled triangle then find the distance

** To explore the gradient on a line, click on the link below:

*** Change the position of the points A and B, make the right-angled triangle then find the gradient. Also, look at the equation of the line, it follows y=mx+b, while m is the gradient and b is the y intercept
