Introduction to Other Straight Line Equation Formats

The video tutorial explores different formats of straight line equations, starting with a recap of the basic y = mx + c format, where m is the gradient and c is the y-intercept. It introduces a new general equation format, y - y1 = m(x - x1), useful for finding equations with a given gradient and point or between two points. The tutorial includes examples demonstrating how to apply these formats to find line equations, emphasizing the importance of understanding different equation forms.

Describe the process of finding the gradient between two points.

How can you rearrange the equation y - y1 = m(x - x1) into the form ax + by = c?

What is the importance of writing the equation in the form ax + by = c?
