Answer:
The coordinates (1,3), (2,5), and (3,7) could represent a linear function.
Explanation:
To have a linear function, the coordinates of the function must have a constant rate of change, or slope, meaning that the x and y-values increase by the same amount for every 2 coordinates.
You can verify that there is a constant rate of change by making an x and y table. Look at the image I attached to my response to see the table I made.
