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

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had
