Match the equation with its graph. -4x - 2y = 8 y = 2x - 4 m = 2, b = -4 The Answer is A. The rate of change is constant in cach table. Find the rate of change. Explain what the rate of change means for the situation. 1. The table shows the cost of a ski rental package for a given number of people. People Cost (5) 4 160 5 200 6 240 16040 = 4 The cost is $40 per person. 7 280 2. The table shows the number of miles driven over time. Time (hours) 4 Distance (miles) 204 6 306 8 408 10 510 51 204=4 The distance is 51 miles per hour. Find the slope of the line. 3. m=-2 m= What is the slope of the line that passes through the pair of points? 3.1-6.1 -2.5 +5.5 3 = 2 5. (-5.5, 6.1), (-2.5, 3.1) 6. (1,7), (10, 1) 1-7-6-2 10-1 = 3 9 What are the slope and y-intercept of the graph of the given equation? 8 7. y=x-m=b=-10 3 8. y 1.9x+2.5 m = 1.9 b = 2.5 9. y=-4x+2 m = -4 b=2 Write an equation of a line with the given slope and y-intercept. 10. m-4.4, b=6.8 y=-4.4+6.8 11. m-5,b-3 y = -5x-3 Write the slope-intercept form of the equation for the line. 12. m= 558 13. b=2 9 m=10 b=-5 8 y=x+ 5 y=108 x What equation in slope intercept form represents the line that passes through the two points? 14. (6.6-25). (8.6-10.5) 8.6-6.6 15. (2.5), (9.2) m= 2-5-3 7 Graph the equation. 16. y=-2x-3 17. y=4x-3 Giselle pays 5240 in advance on her account at the athletic club. Each time she uses the club, $15 is deducted from the account. Model the situation with a linear function and a graph.
