For this exercise it is important to remember that, given a point
, "x" is the the x-coordinate of the point and "y" is the y-coordinate of the point.
In this case, Ms. Juhal has the following points:
1) Point

Where you can identify that:

2) Point

Where:

3) Point

Where you can observe that:

4) Point

Where:

Therefore, knowing the coordinates of each point, you can plot them and connect them in order (Observe the picture attached).
Finally, you can identify that the shape created is a Triangle.
