Finding the Slope: Exploring Positive, Negative, Zero, and Undefined Slopes

The video tutorial explains the concept of slope, which is the inclination of a line. It covers the properties of slope, including positive, negative, zero, and undefined slopes. The tutorial demonstrates how to calculate slope using the rise over run method and the formula y2-y1/x2-x1. It provides examples of calculating negative, positive, and undefined slopes, emphasizing the importance of maintaining consistent order in calculations.

What does a positive slope indicate about the direction of a line?

• The line is going up to the right.

• The line is horizontal.

• The line is going down to the right.

• The line is vertical.
