A function is an equation that has only one answer for y for every x. This means that:
Set A and Set C are functions because their y values don’t repeat.
Set B is NOT a function because the 2 in the y values repeats twice.
Hope I helped!
The decimal representation for 4/5 would be,
0.8
Hope it helped. It's all I could do.
Assuming a and b are parallel
<5 = <9 false
<1 = <12 false
<1 = <8 true
<3 = <7 true
All the x coordinate values
