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)
Hi there. Your last question you learned the procedure for computing the midpoint. Can you apply that to these points?
Do you remember what the procedure was?
there is no correct answer in the solutions you give though... isn't point V(-2,-3) ?
Your previous question was asking the procedure; you got the answer, A. What did that say?
it said Calculate the average of the x-coordinates and the average of the y-coordinates of the endpoints.
Right. So, let's first calculate the average of the X coordinates. First, what are the two x coordinates?
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.
I did copy the numbers correctly
Hmm.. OK, are you sure you copied answers C and D correctly? They're the same.
here is answer d (x/2, (y-3)/2)
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?
V(-2, -6) and W(x+2, y+3)
Those are the complete endpoints. What are the X coordinates?
Remember that for a point, it's (x, y) ... the first coordinate is X, and the second is Y.
So x would be -2 and y would be -y
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?
that's the Y coordinate of the first point.
We want the X coordinate of the second point.
