If K is midpoint of segment HL, then its coordinates can be calculated by the formula

$x_K=\dfrac{x_H+x_L}{2},\\ \\y_K=\dfrac{y_H+y_L}{2}.$

You are given coordinates of points H and K: H(1,-7) and K(-9,3), then

$-9=\dfrac{1+x_L}{2},\\ \\3=\dfrac{-7+y_L}{2}.$

Find the coordinates of point L:

$-9=\dfrac{1+x_L}{2}\Rightarrow 1+x_L=-18,\ x_L=-19;$

$3=\dfrac{-7+y_L}{2}\Rightarrow -7+y_L=6,\ y_L=13.$

answer: true

step-by-step explanation:

the vertical change is between two points on a line and the horizontal change is called the run. i hope this
