Answer 1

The comma separates x and y coordinates. So -1.5 is the x coordinate and 2.8 is the y coordinate. Therefore, the comma makes them an ordered pair and an exact location on a graph.

Answer 2

Step-by-step explanation: The comma is to separate the two numbers. for example: 1st point, 2nd point. hope this helped!
