To determine the correct graph that represents the points (1,5), (2,7), (3,9), and (4,11), we first need to find the relationship between these points.

Let's analyze the points:

  1. (1, 5)
  2. (2, 7)
  3. (3, 9)
  4. (4, 11)

You can see that the y-values are increasing by 2 for each increase of 1 in the x-values:

  • From (1,5) to (2,7): 5 + 2 = 7 (increase of 2)
  • From (2,7) to (3,9): 7 + 2 = 9 (increase of 2)
  • From (3,9) to (4,11): 9 + 2 = 11 (increase of 2)

This pattern suggests that the equation of the line can be expressed in the form of a linear function, specifically:

\[ y = 2x + 3 \]

Where:

  • The slope (m) is 2 (this indicates the line rises 2 units for every 1 unit it moves horizontally).
  • The y-intercept (b) is 3 (the point where the line crosses the y-axis).

Now, let’s visualize:

  • At x = 1, y = 2(1) + 3 = 5 (correct)
  • At x = 2, y = 2(2) + 3 = 7 (correct)
  • At x = 3, y = 2(3) + 3 = 9 (correct)
  • At x = 4, y = 2(4) + 3 = 11 (correct)

So, the correct graph would show a straight line passing through these four points:

  • (1,5)
  • (2,7)
  • (3,9)
  • (4,11)

Without the actual images, I cannot specify which graph corresponds to this equation. However, you should look for a straight line that passes through all the four indicated points.
