Understanding Slopes

The video tutorial explains how to find the slope of a line by using the ratio of the vertical rise to the horizontal run. It emphasizes the importance of identifying two points on the line that intersect the grid corners and considering the scale factor when calculating the slope. The tutorial also covers different types of slopes, including positive, negative, undefined, and zero slopes, and explains special cases such as vertical and horizontal lines.

What is the first step in finding the slope of a line?

• Identify two points on the line

• Calculate the area under the line

• Find the midpoint of the line

• Determine the length of the line
