5.2 Defining Slope Lesson Essential Question: Can you calculate slope using rise over run and the formula for finding slope? "Bel lringer" Gi ven the equation 4x + y = 36 (8, ?) Find y. a) y = 3 b) y = 4 c) y = 5 d) y = 6
2
What word(s) come to mind when you hear the word SLOPE? _____________________ is the ratio of vertical rise to horizontal run. Fo rmula for Slope: y 2 - y 1 x2 - x 1 Ex amples
3
What do all of these lines have in common? All of these lines have ___________________________ slope.
4
What do all of these lines have in common? All of these lines have ___________________________ slope.
6
Bellringer Fi nd the slope of a line containing the points ( -1, 7 ) and (8, -3) a.) - 9 b.) -10 / 9 c.) -9 / 10 d.) - 10 The line below has... a.) positive slope b.) undefined slope c.) zero slope d.) negative slope
7
1.)Plot the point (1,2) 2.)Graph a line with a slope of 3/4 from that point.
8
Horizontal Lines Step 1.) Draw a horizontal line on the graph below Step 2.) Pick any two points on the line Step 3.) Calculate the slope from those two points What is the slope of a horizontal line?
9
Vertical Lines Step 1.) Draw a vertical line on the graph below Step 2.) Pick any two points on the line Step 3.) Calculate the slope from those two points What is the slope of a vertical line?
