CHAPTER 4 & 5 REVIEW 1. Determine if each of the following equations represents a direct variation. If the equation is direct then find the constant of variation. (A) 2 y 5 x 1 (B) 5 x 6 y 0 (C) y 13 x Yes, 1/3 Not a representation Yes, 5/6 2. Find the rate of change for each situation: (A) Over a 4 week period the grass grew 2 inches. ½ in per week (B) It took Sammie 45 minutes to type a 9000 word essay. 200 words per minute 3. Determine the slope of each of the 4. Determine the slope of a line that following lines. passes through each of the given set of points. Line A m = 5/4 Line B Line C (A) (1, 5), (3, 4) -1/2 Vertical Line: m = (B) (1, 0), (1, -5) Undefined undefined (C) (2, 3), (1, 6) -3 (D) (0, -4), (-3, -4) 0 Line D horizontal line: m = 0 5. Determine the x– and y-intercepts of the line in each graph: (A) (B) x-int (-6, 0), y-int (0, 3) x-int (5, 0) y-int (0, 4) 6. Determine the x– and y-intercepts of the graph of each equation: 4 x 6 y 8 x-int (2, 0), y-int (0, 4/3) 7. Write an equation in Slope-Intercept Form and Standard Form of a line with the given slope and y-intercept: m = 3, b = -5 Slope Intercept: y = 3x -5, standard form: y – 3x = -5 CHAPTER 4 & 5 REVIEW 8. Find the slope and y-intercept of each equation: 3x 2 y 8 Slope: 3/2, y-int (0, -4) 12. Write an equation in Point-Slope Form of a line that passes through the given point and has the given slope: m = 13 , (-6, -7) y + 7 = 1/3(x+6) 13. Write an equation in Standard Form of a line that passes through the given point and has the given slope: m = 1, (-2, 3) y–x=5 14. Write an equation in Point-Slope Form of a line that passes through the two points: (4, 1), (5, 6) y – 6 = 5(x – 5) OR y – 1 = 5 (x-4) 15. Write an equation in Standard Form of a line that passes through the two points: (3, 4), (5, 10) y – 10 = 3 (x – 5) OR y-4 = 3 (x – 3) 18. Make a scatter Plot of the data. Draw a line of fit. Write an equation of the line. Line of Best Fit: Something close to y = 5x-4 (remember to have the calculator graph to check) X 0 2 4 8 10 Y -2 6 15 38 50
