Which ordered pairs represent points on the graph of this equation? Select all that apply.

y=3x+2

1 answer

To determine which ordered pairs represent points on the graph of the equation \( y = 3x + 2 \), we can substitute the x-values from the ordered pairs into the equation and check if the corresponding y-values match.

Let's say we have the following ordered pairs to evaluate:

  1. \( (0, 2) \)
  2. \( (1, 5) \)
  3. \( (2, 8) \)
  4. \( (3, 11) \)
  5. \( (4, 14) \)
  6. \( (-1, -1) \)

Now let's evaluate each pair:

  1. For \( (0, 2) \): \[ y = 3(0) + 2 = 2 \] This matches, so \( (0, 2) \) is a point on the graph.

  2. For \( (1, 5) \): \[ y = 3(1) + 2 = 5 \] This matches, so \( (1, 5) \) is a point on the graph.

  3. For \( (2, 8) \): \[ y = 3(2) + 2 = 8 \] This matches, so \( (2, 8) \) is a point on the graph.

  4. For \( (3, 11) \): \[ y = 3(3) + 2 = 11 \] This matches, so \( (3, 11) \) is a point on the graph.

  5. For \( (4, 14) \): \[ y = 3(4) + 2 = 14 \] This matches, so \( (4, 14) \) is a point on the graph.

  6. For \( (-1, -1) \): \[ y = 3(-1) + 2 = -3 + 2 = -1 \] This matches, so \( (-1, -1) \) is a point on the graph.

Summary of ordered pairs that are on the graph of \( y = 3x + 2 \):

  • \( (0, 2) \)
  • \( (1, 5) \)
  • \( (2, 8) \)
  • \( (3, 11) \)
  • \( (4, 14) \)
  • \( (-1, -1) \)

Thus, all the given pairs are valid points on the graph of \( y = 3x + 2 \).
