The midpoint of jk is point (-1,8). one endpoint is j(4, -15). which equations can be solved to determine the coorinates of other endpoint, k? select two options

(-6,31)

Step-by-step explanation:

We have two points j,k whose midpoint is (-1,8).

Formula for calculating midpoint of two points (x1,y1) and (x2,y2) is

So we already have midpoint as  (-1,8).One of the point here is (4, -15) so let the other point be (l,k).

Hence the other point is (-6,31).

the answer to this is a. a^2 + b^2 = c^2
