Ответ:
The other end point would be (10, 1).
In order to solve these, you must look at the formula for finding the midpoint.
midpoint(x) = (x1 + x2)/2
midpoint(y) = (y1 + y2)/2
Using these two formulas, we can solve for the second point. Let's start with the x value.
midpoint(x) = (x1 + x2)/2 > plug in known values
6 = (2 + x2)/2 multiply both sides by 2
12 = 2 + x2 > subtract 2
10 = x2
Now do the same for y.
midpoint(y) = (y1 + y2)/2 > plug in known values
-1 = (-3 + y2)/2 > multiply both sides by 2
-2 = -3 + y2 > add 3 to both sides
1 = y2
Given these two point, we now have the ordered pair of (10, 1) for the other end point.
