Answer:
The equations represent circles that result in the same graph.
Step-by-step explanation:
we have

Divide by -10 both sides
 -----> equation A
 -----> equation A
This is the equation of a circle centered at origin with radius 
and
 
 
Divide by 5 both sides
 -----> equation B
 -----> equation B
This is the equation of a circle centered at origin with radius 
equation A and equation B are equal
therefore
The system has infinite solutions, because the equations represent circles that result in the same graph.

Answer:
D. Collinear 
Step-by-step explanation:
Three points lying on a line are collinear because they share the same line. 
the rest of the options can be ruled out because the points can not be congruent due to lack of distance information and the same goes for midpoint and equal.
