  1. Chapter 3 REVIEW Sections 3.3, 4.1, 3.4, 3.1

  2. Problem #1 • Find the slope of the line that passes through (0, -4) ad (3, 2)

  3. Problem #2 • Find the slope of the line that passes through (0, 2) and (0, 4).

  4. Problem #3 • Find the rate of change represented in the graph.

  5. Problem #4 • Find the rate of change represented in the graph.

  6. Problem #5 • The average cost of phone increased from $99 in 2007 to $299 in 2013. Find the average rate of change in the cost. Explain what it means.

  7. Problem #6 • Graph the equation y = x

  8. Problem #7 • Graph the equation y = 4/3x

  9. Problem #8 Suppose y varies directly as x. Write a direct variation equation that relates x and y. Then solve. If y=15 when x=2, find y when x=8.

  10. Problem #9 • Suppose you earn $127 for working 20 hours. • Write a direct variation equation relating your earnings to the number of hours worked. • How much would you earn for working 35 hours?

  11. Problem #10 Graph the equation by using a table. Y = -x + 2

  12. Problem #11 Graph the equation by using x- and y- intercepts. 2x – 3y = 12

  13. Problem #12 Write an equation of a line in slope-intercept form with the given slope and y-intercept. Then graph the equation. m=4; y-intercept: (0, -2)

  14. Problem #13 Rewrite an equation of a line in slope-intercept form. Then graph the equation. 3x + 4y = 8

  15. Problem #14 Write an equation in slope-intercept form for the total cost of skiing for h hours with one lift ticket.
