Question

What are the coordinates of the midpoint between (3, -7) and (-5, 2)?

A. (-2, -5)
B. (-1, -2.5)
C. (-4, -4.5)
D. (1, 2.5)

Answer 1

What are the x coordinates of each point?

Answer 2

im not sure

Answer 3

For any point, the x coordinate is the first number listed

eg: (3,-7) has an x coordinate of 3

does this make sense?

Answer 4

oh okay
so it would be 3 and -5

Answer 5

yep

Answer 6

add up those x coordinates and you get what?

Answer 7

-2

Answer 8

now cut that in half to get what?

Answer 9

-1

Answer 10

so the midpoint has an x coordinate of -1

Answer 11

the y coordinate of the midpoint is calculated the same way: add up the y values, then divide that result in half

Answer 12

so it would be D, correct?

Answer 13

oh no sorry

Answer 14

the midpoint has an x coordinate of -1

Answer 15

yeah it would be B, forgot about the negatives

Answer 16

for the y coordinate

-7+2 = -5

then cut that in half to get -5/2 = -2.5

Answer 17

`it would be B`
correct

Answer 18

thanks for the help!

Answer 19

sure thing
