The domain is all of the x values in a set and the range is all of the y-values in a set.
If you have a bunch of points such as (3,6), (7,2), (1,5) the domain would be stated as D={3, 7, 1} and the range would be stated as R={6,2,5} If you have a line, then the domain and range would be set up differently. For example, if you have a line with end points at (-3,2) and (5,8) then the domain would be D=(-3,5) and the range would be R=(2,8)

Find the coordinates of the midpoint of a segment with the given endpoints. A (-1, 4) and B (-5, -2)
ANEK [815]

Step-by-step explanation:

solution,

midpoint between A(-1,4) and B(-5,-2)=

(X1 + X2 ÷2, Y1 + Y2 ÷2)

=(-1-5÷2 , 4-2)

=(-6÷2 ,2÷2)

=(-3 , 1)

The quotient is 5 and

1/2. It isn't asking for another solution, just the fraction.
