Which methods could you use to calculate the y-coordinate of the midpoint of a vertical line segment with endpoints at (0, 0) and (0, -12)?

check all that apply

a. add the endpoints
b. count by hand
c. divide 12 by 2
d. divide -12 by 2

the answer is the option D

Divide by

Step-by-step explanation:

we know that

The formula to calculate  the y-coordinate of the midpoint between two points  is equal to

where y1,y2 are the y-coordinates of the two points

In this problem we have

Points and

so

Substitute the values in the formula

therefore

the answer is the option D

Divide by

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
