Answer:
D
Step-by-step explanation:
Replace R1 with 1 and R3 with 0 you have -2(1)+0 which equals 0 and that matches matrix II. Repeat the process with the other numbers in R1 and R3 and they all come out equal therefor the answer is D.
so 253 doubles is 506, 506 divided by two = 253
therefore the answer will be '' 506 divided by 2 = 253''
The distance between the 2 points is approximately 8.25
