📘 MTH101 – Lecture 4: Line

In this lecture, we dive into one of the most important topics in coordinate geometry — Lines. You will learn how to represent and analyze straight lines using different mathematical forms.

🔹 What you will learn:
• What is a line in coordinate geometry
• Understanding slope (gradient) of a line
• Point-Slope Form of a line
• Slope-Intercept Form of a line
• How to convert between different forms
• Graphing lines on the coordinate plane

📌 Key Concepts Explained:

✔️ Line:
A straight path that extends infinitely in both directions. It can be represented using equations and graphs.

✔️ Point-Slope Form:
Used when you know a point and the slope of the line.
Formula:
y − y₁ = m(x − x₁)

✔️ Slope-Intercept Form:
The most common form to represent a line.
Formula:
y = mx + c
Where:
m = slope
c = y-intercept (where the line crosses y-axis)

This lecture will help you understand how to easily solve and graph line equations step by step.

🎯 Perfect for beginners and Virtual University students preparing for exams.
