Calculating Slope and Analyzing Line Relationships

The video tutorial covers the concept of slope, explaining it as the rate of change and rise over run. It discusses how to calculate slope from graphs or coordinates, and how to identify parallel and perpendicular lines based on their slopes. The tutorial includes practical examples and exercises to reinforce understanding, and introduces memory aids like 'Hoy' and 'VUX' for horizontal and vertical lines.

What is another term for slope?

• Vertical shift

• Gradient

• Rate of change

• Angle of inclination
