Question

When given the ordered pair (4,-9), Michelle said to start at the point of origin, so left 4 units and up 9 units. What's wrong with her thinking?

Answer 1

Since she starts at the point of origin (0,0), she took the points in opposite directions.

The correct form is right 4 units and down 9 units.

Positive values in the x-axis are to the right, and negative values on the y-axis are down.
