M8G1. Students will understand and apply the properties of parallel and perpendicular lines. a. Investigate characteristics of parallel and perpendicular lines both algebraically and geometrically. Part I Please follow the directions carefully. 1. Pick any two ordered pairs? Example (1, 2) & (3, 4) 2. Find the slope of the line connecting these two points a. Using a table with difference of y-values vs. x-values b. Using the formula m = (y2 -y1)…show more content…
Using the formula for slope find the slope of the following: 1. (1, 15), (2, 25) 2. (2, 25), (3, 35) 3. (1, 15), (3, 35) 4. (3, 35), (4, 45) Assume that the total cost is a linear function of the number of packages ordered. 5. Write an equation of the line that contains the data points. Show the work that led to your answer. 6. What is the slope of the line that contains the data points? 7. What does the slope represent in the context of this problem? 8. What is the y-intercept of the line that contains the data points? 9. What does the y-intercepts represent in the context of this
