Answer is D.
As M is the midpoint of A and B; denote A(x,y); then x and y have to matched the two equations below:
(x- 3) : 2 = 2 <=> x = 7 and
(y +10) : 2 = 6 <=> y = 2
Conclusion : A (7,2)
Student A is wrong and Student B is correct.
How?
- Direction is saying to construct a line that passes through C
- The last step is enough to describe that A is wrong.
- Its saying to swing an arc(Should be line).
- On the other hand Student B has done correct
- By passing point through C and G it satisfies our required construction.
it would take them 5 hours and 70 seconds
