1 SLOPE

2 The slope ( m ) of a line is a measure of how steep or slanted the line is. Just think of the pitch of a roof or steepness of a hill.

3 SLOPE The slope ( m ) of a line is a measure of how steep or slanted the line is. Just think of the pitch of a roof or steepness of a hill. You can find slope from : - two coordinate points - a given linear equation - a given graph

20 The slope ( m ) of a line is a measure of how steep or slanted the line is. Just think of the pitch of a roof or steepness of a hill. You can find slope from : - two coordinate points - a given linear equation - a given graph When a graph is given, find some intersection points and either count the slope or use the slope from 2 points formula.

21 SLOPE The slope ( m ) of a line is a measure of how steep or slanted the line is. Just think of the pitch of a roof or steepness of a hill. You can find slope from : - two coordinate points - a given linear equation - a given graph When a graph is given, find some intersection points and either count the slope or use the slope from 2 points formula. If you count the slope remember up and right are positive moves, down and left are negative moves.

23 Counting slope from a graph :

24 1. Find a starting point

25 Counting slope from a graph : 1. Find a starting point 2. Move up or down first to find change in y +5

26 Counting slope from a graph : 1. Find a starting point 2. Move up or down first to find change in y 3. Move left or right to find change in x +5 +2

27 Calculating slope from a graph :

28 1. Label your coordinate points
