Answer:

D. y = 5x - 8.5 AND C. y = 4x - 4

Step-by-step explanation:

You can test to see which equation includes (4.5, 14) by substituting 4.5 for x in each equation. Since more than one answer could be correct, test each equation. To test D, for example, you would do this:

  1. y = 5x - 8.5
  2. y = 5(4.5) - 8.5
  3. y = 22.5 - 8.5
  4. y = 14
