1. Warm Up 1) 2)

4. Finding the slope of a line given a graph

5. Example 1 Slope (m) =

6. Example 2 M =

7. 2 parts to a linear equation 1. Slope = = m 2. Y intercept = b *the point where the graph crosses the y- axis Y intercept = B=

8. Let’s try a few Work in teams to find the slope and y-intercept of the graphs

9. SLOPE INTERCEPT FORM

10. Graphing from an equation in slope intercept form 1.Start at your y-intercept (b) 2.Go up and over by the slope (m) always to the right first *if the slope is a whole number only go over by 1 ie: m=2 go up 2 over 1

11. Y= 3x - 2

12. FINDING THE SLOPE OF A LINE GIVEN 2 POINTS

13. FOR EXAMPLE Find the slope of the line that goes through (1,1) and (3,4) First label the x 1 and x 2 and y 1 and y 2 values then put them into the slope equation

14. FIND THE SLOPE The line goes through points (-2,-5) and (-1,3) M= The line goes through (-3,5) and (4,9) M=

17. Given a slope of 3 and a line that passes through point (-1,6) find the slope intercept form of the line Y=

18. FIND THE SLOPE INTERCEPT GIVEN 2 POINTS (1,-3) and (5,-3)
