1. + CHAPTER 5 REVIEW

2. + U-Haul charges $25 a day to rent a moving truck and $2 per mile. A) Write an equation that gives total cost as a function of the distance (miles). B) What is the cost to rent the truck if I travel 40 miles in 1 day?

3. + A) y = 2x + 25 B) y = 2(40) + 25 = $105

4. + Write the equation of the line:

5. +

6. + Write an equation of the line that passes through the given point and is perpendicular to the given line: (8, -1); y = 2x - 6

7. + Remember to use the OPPOSITE AND RECIPROCAL SLOPE!!

8. + Write the equation of a horizontal line that passes through the point: (2, 14)

9. + y = 14 Remember, the slope is 0… so the equation is: y = 0x + 14, BUT! you can simplify that!!

10. + Write an equation of the line that passes through the given point and is parallel to the given line: (2, 5); y = 4x + 9

11. + y = 4x – 3 **Steal the Slope: 4

12. + Write the equation for a linear function f with the given values: f(-2) = 4 and f(6) = 12

13. + y = x + 6 Remember, 1 is the invisible number for multiplication!

14. + Write an equation of the line that passes through the given points: (6, -5) and (6, 10)

15. + x = 6 **the slope is undefined!!

16. + Write the equation in slope- intercept form: 10x – 5y = 20

17. + y = 2x – 4 **Solve for y!!

18. + The table shows the points scored in basketball game. A) Make a scatterplot B) Write the equation of the line of best fit C) Use your equation to predict the number of points scored after 60 minutes (the entire game) Time (min) 2102238 Points281824

19. + Graph by writing in slope- intercept form. Then, identify the slope and y-intercept. 2x – 4y = 12

20. + Solve for y first! Slope: y – intercept: (0,– 3)

21. + Graph by writing in slope- intercept form. Then, identify the slope and y-intercept. y = –4

22. + y = –4 y = mx + b y = 0x – 4 Slope: 0 / 1 or 0 y – intercept: (0,– 4)
