To write an ordered pair, we must have two coordinates: one referring to the ordinate axis, and the other referring to the abscissa axis.

We use X for the ordinate axis (horizontal) and Y for the abscissa axis (vertical), and write the point as (x, y).

We solved this exercise and according to the system, got x = -2 and y = -3, do you remember?

So, we have two coordinates: one in the ordinate axis (x = -2), and the other in the abscissa axis (y = -3).

We also can write this as (-2, -3), like an ordered pair.

To draw it in the graph, first we'll need to follow the horizontal axis and mark the point -2. After that, we will follow the vertical axis and mark the point -3. Now, you can draw a dotted line where the axes have this value.
