  4. A swimming pool is being drained at a rate of 720 gallons per hour. The table shows the function relating the volume of water in a pool and the time in hours that the pool has been draining. Page 155 Example 3

  5. Page 157 #5 and 6

  6. Finding the x- intercept 1) Substitute 0 for y 2) Then solve for x 3) (x, 0)

  7. Finding the y-intercept 1) Substitute 0 for x 2) Then solve for y 3) (0, y)

  8. Find the x and y intercepts Then graph the line 3x+ 2y= 6

  9. Find the x and y intercepts Then graph the line y = x + 3

  10. Find the x and y intercepts Then graph the line y= 1x+2 3

  11. p. 159 #50 • An amusement parks charges $50 for admission before 6pm and $20 for admission after 6pm. On Saturday, the park took in a total of $20,000. • Write an equation that represents the number of admissions that may have been sold. Let x represent the number of admissions sold before 6pm, and let y represent the number of admission sold after 6pm. • Graph the equation • Find the x- and y-intercepts of the graph. What does each intercept represent

  12. Journal Can a line only have one intercept or must it always have an x-intercept and a y-intercept?
