get a common denominator which is 24
3 7/8 = 3 21/24
6 /4 = 6 6 /24
3 21/24 - 6 6 /24
big number minus small number take sign of larger
6 6/24
- 3 21/24
-------------
5 30/24
3 21/24
--------------
2 9/24
2 3/8
the sign of the larger is negative
-2 3/8
There was a 20% decrease
48/60 × 100 = 80%
100 - 80 = 20%

Substitute the values in:

Point-slope form is

Substitute (it doesn't matter which point you choose; I chose (4,5):
Therefore, the answer is D.
