The video tutorial explains the general equation of a straight line, y = mx + c, where m is the gradient and c is the y-intercept. It covers how to calculate these values using examples, including a practical application of converting Celsius to Fahrenheit. The tutorial emphasizes understanding the gradient's role in determining the line's steepness and direction, and the y-intercept as the point where the line crosses the y-axis.
