Answer:

Step-by-step explanation:
The coordinates are:

The parallelogram is attached below.
To verify if these coordinates form a parallelogram, we show that:
Using Distance Formula




Since AB=CD; and AC=BD, the coordinates A, B, C, and D form the vertex of a parallelogram.
Answer:

Dividing is the same as putting numbers into a fraction. This is N/8. We don't get the answer until we figure out what N is equal to.
