Calculating Slope
Count the Slope!
Count the Slope!
rise = 4
run = 5
Slope = rise run
Slope = 4/5
Count the Slope!
• No rise at all means your numerator will be zero.• Slope = 0• Think of hiking along a flat ground. It requires zero effort!
Slope of Horizontal Lines
• No run at all means your denominator will be zero.• Try this in your calculator. 50 ÷ 0. What do you get?• Slope = undefined• Think of hiking down a perfectly vertical cliff. It is impossible! You would die.
