Question

K is the midpoint of jl h has coordinates 1,-7 and k has coordinates 9,3 find the coordinates of l

Answer 1

Question is not written properly neigher picture is provided so I rearranged question as follows:

K is mid point of JH where coordinate of the end points are (1,-7) and (9,3). Now question says to find the mid point of the line joining points (1,-7) and (9,3).

Answer:

we just need to apply mid point formula:

Mid point $= \left(\frac{\left(x_1+x_2\right)}{2},\frac{\left(y_1+y_2\right)}{2}\right)$

There (x1,y1) and (x2,y2) are the given end points. So plug the given values.

$= \left(\frac{\left(1+9\right)}{2},\frac{\left(-7+3\right)}{2}\right)$

$= \left(\frac{\left(10\right)}{2},\frac{\left(-4\right)}{2}\right)$

$= (5,-2)$

Hence final answer is (5,-2).
