Math is a really fun thing Slope and Rate of Change can be stressful But with My help it can be fun!

Using This Section In Everyday Life Use slope to figure out how to angle a ladder against a building to keep safe. Example for a 12ft. Ladder the base of the Ladder should be 3ft from the wall.

Section 2 Slope and Rate of Change To find slope you must use this formula M= The slope of a non vertical line is the ratio of vertical change(the rise) to horizontal change (the run). (Rise) (Run)

Finding the Slope of a Line Y (-3,5) 5 -4 (2,1) X Find the slope of the line passing through (-3,5) and (2,1) Let (x1,y1) = (-3 ,5) and Let (x2, y2) = (2,1) Answer= -4 over 5

Classification of Lines By Slope A line with a positive slope rises from left to right A line with a negative slope falls from left to right A line with a slope of zero is horizontal A line with an undefined slope is a vertical

Classification of Lines Continued Positive Slope Negative Slope Zero Slope Undefined Slope
