SLOPE LESS 5-1

MATH VOCABULARY Slope: The diagonal “slope” of a line on a graph that runs through given points

UNDERSTANDING SLOPE Slope = m m = rise = up/down run right

SLOPE OF A LINE POSITIVE SLOPE NEGATIVE SLOPE

SLOPE OF A LINE UNDEFINED SLOPENO SLOPE = 0

COUNTING UNITS TO FIND SLOPE When we count units… we count the rise between two clearly identified points run

COUNTING UNITS TO FIND SLOPE M =

USING COORDINATES TO FIND SLOPE Another way to find slope… by slope formula m = y² - y¹ x² - x¹

USING COORDINATES TO FIND SLOPE (2, 1) and (5, 7) m = y² - y¹ x² - x¹ Label & Plug in: m = 7 – 1 5 – 2 (4, 0) and (-1, 5) m = y² - y¹ x² - x¹ Label & Plug in: m = 5 – 0 -1 – 4

PRACTICE… Find the slope of the given points: a)(1, 2) and (4, 2) b)(5, 8) and (-3, -4) c)(5, -2) and (5, 8)
