Understanding Parallel Lines and Calculating Parallel Lines

The video tutorial explains the concept of parallel lines, emphasizing that they never intersect and have the same gradient but different y-intercepts. It covers how to calculate the gradient using the rise over run method and how to find the equation of a line using y=mx+c. The tutorial also demonstrates how to determine if two lines are parallel by comparing their gradients and how to find the equation of a parallel line passing through a specific point. Complex problems involving parallel lines are also addressed.

How can you determine if two lines are parallel using their equations?

What is the formula for calculating the gradient from a graph?

What is the importance of the y-intercept in the equation of a line?

Explain how to find the equation of a line given two points on that line.
