How to Find a Point on a Line | Leaving Cert Maths | Coordinate Geometry

Описание: Are you studying for your Leaving Cert and need a quick refresher on Coordinate Geometry? In this video, we tackle a common exam-style question: finding the value of an unknown constant (p) when a point lies on a given line.

We walk through the step-by-step process of substituting coordinates into a linear equation and solving for the missing variable. This method works whether you are dealing with a straight line, a circle, or a curve!

What we cover:

Understanding the (x, y) coordinates of a point.

Substituting values into the equation of a line.

Solving basic algebraic equations to find the constant.

Practical tips for the Leaving Cert Maths exam.

Perfect for Junior Cycle and Leaving Cert (Higher and Ordinary Level) students looking to master the basics of coordinate geometry.
