A rhombus has two equal sides
See https://web2.0calc.com/questions/please-help_96053.
First find the common denominator. It would be 24. For 8 to get to 24 you have to multiply it by 3. So 8*3=24 and 5*3=15. For 6 to get to 24 you have to multiply it by 4. So 6*4=24 and 1*4=4. Our fractions are now at 15/24 and 4/24. 15+4 is 19 and 15-4 is 11. Your answers are 19/24 and 11/24.
That would be B.
The set of points are all on the line which is a bisector.
Just draw one empty circle for 1 and then a filled circle for -1 so then it's 1-1 which equals 0
