Question

If the endpoints of `bar(AB)` have the coordinates A(9, 8) and B(-1, -2), what is the midpoint of `bar(AB)`?

Answer 1

To solve this problem you must apply the proccedure shown below:

1. You have the following points given in the problem above:

`A(9,8)\\ B(-1,-2)`

2. To find the midpoint, you must apply the formula that is used for calculate it. This is:

`m=((x1+x2)/(2), (y1+y2)/(2) )`

Where:

`x1=9\\ x2=-1\\ y1=8\\ y2=-2`

3. Now, you must substitute these values into the formula for calculate the midpoint, as following:

`m=((9+(-1))/(2) ,(8+(-2))/(2) )\\ m=(4,3)`

Therefore, the answer is:
`m=(4,3)`
