Introduction To Slope
Slope (Middle box) Measures steepness of a line Rate of change “m” = symbol for slope 𝑣𝑒𝑟𝑡𝑖𝑐𝑎𝑙 𝑐ℎ𝑎𝑛𝑔𝑒 ℎ𝑜𝑟𝑖𝑧𝑜𝑛𝑡𝑎𝑙 𝑐ℎ𝑎𝑛𝑔𝑒 = 𝑑𝑖𝑓𝑓 𝑖𝑛 𝑦 𝑑𝑖𝑓𝑓 𝑖𝑛 𝑥 = ∆𝑦 ∆𝑥 = 𝑟𝑖𝑠𝑒 𝑟𝑢𝑛 Formula: 𝑦 2 − 𝑦 1 𝑥 2 − 𝑥 1 Formula for a line: 𝑦=𝑚𝑥+𝑏 slope
Slope #1 - Positive Slope Always look at the slope from left to right “Uphill” Ex: m = 3, 2 3 , 10 7 , 9, 2 1
Slope #2 - Negative Slope Always look at the slope from left to right “Downhill” Ex: m = -1, − 4 7 , − 5 2 , -6, − 3 1
Slope #3 - Zero Slope Horizontal Line Numerator is 0 Ex of slope: m = 0, 0 8
Slope #4 - Undefined Slope No slope to the line Vertical Line Denominator is 0 Ex of slope: m = − 7 0 , 5 0
