The slope of a line is a measure of how steep it is. It gives you information about how quickly the line is rising or falling as you move along it.
To understand the meaning of slope, you need to know how it is calculated. It is determined by the ratio of the change in vertical distance (y-axis) to the change in horizontal distance (x-axis) between two points on the line.
The link you provided, www.purplemath.com/modules/slope.htm, will give you a more detailed explanation and examples of how to calculate and interpret slope. I recommend visiting the website as it provides step-by-step explanations and graphical interpretations to help you understand the concept of slope better.
