Understanding Slope and Line Types

The video tutorial explains how to find the slope of a line given two points and determine if the line is increasing, decreasing, horizontal, or vertical. It provides examples for each type of line: a decreasing line with a negative slope, a vertical line with an undefined slope, an increasing line with a positive slope, and a horizontal line with a zero slope. The tutorial uses coordinate plane illustrations to enhance understanding.

Why is the slope of a vertical line undefined?

• Because both changes are zero

• Because the line is horizontal

• Because the change in X is zero

• Because the change in Y is zero
