54 3/11...
54 is ur whole number
3/11 = 0.27 with a line over the 27 because it is repeating
so ur answer would be : 54.27...with a line over the 27
Perpendicular means the slopes are opposite inverse of each other
If line a is slope 2, the perpendicular line to Line a would have a slope - 1/2
Difference in y over difference in x gives slope. If they are opposite inverse values the lines are perpendicular. ( in this case the answer is true.)
The second one seems about right.
