Answer:
(-7,-4)
Explanation:
Draw the point on a graph.
If it is positive, and it is rotated 180 degrees, that means it would turn halfway around and then stop, while full circle it would end up right where it started.
When it does this on a full graph, it turns into a negative point, since it is on the opposite side of the origin, we find the opposite numbers.
The answer is (-7,-4)
Hope this helps!
