Question

Given segment VW with endpoints V(-2, -6) and W(x+2, y+3), find the coordinates of the midpoint.

A-(x, y-3)
B-(x/2, y/2)
C-(x-2, y-3)
D-(x-2, y-3)

Answer 1

Hi there. Your last question you learned the procedure for computing the midpoint. Can you apply that to these points?

Answer 2

Okay

Answer 3

Do you remember what the procedure was?

Answer 4

there is no correct answer in the solutions you give though... isn't point V(-2,-3) ?

Answer 5

ktklown i do not

Answer 6

Your previous question was asking the procedure; you got the answer, A. What did that say?

Answer 7

it said Calculate the average of the x-coordinates and the average of the y-coordinates of the endpoints.

Answer 8

Right. So, let's first calculate the average of the X coordinates. First, what are the two x coordinates?

Answer 9

Also, are you sure you copied the numbers in the problem correctly? As henkjan noted, the answer to the problem you posted is not one of the multiple choice selections.

Answer 10

I did copy the numbers correctly

Answer 11

Hmm.. OK, are you sure you copied answers C and D correctly? They're the same.

Answer 12

no i didn't sorry

Answer 13

here is answer d
(x/2, (y-3)/2)

Answer 14

OK. great. Let's get back to solving the problem. As you said, the goal is to first average the x coordinates of the endpoints. So, what are the x coordinates of the endpoints?

Answer 15

V(-2, -6) and W(x+2, y+3)

Answer 16

Those are the complete endpoints. What are the X coordinates?

Answer 17

Remember that for a point, it's (x, y) ... the first coordinate is X, and the second is Y.

Answer 18

So x would be -2 and y would be -y

Answer 19

We want the two x coordinates. The x coordinate of the first point is -2, like you said. What's the x coordinate of the second point?

Answer 20

-6

Answer 21

that's the Y coordinate of the first point.

Answer 22

We want the X coordinate of the second point.
