find the coordinates of J if K(-5,10) is the midpoint of JL and L has coordinates of (-8,6)

Answer 1

-8-(-5)=-3 so -5-(-3)-2

6+4=10+4=14

(-2,14)

Answer 2

Midpoint formula states that the x and y coordinates are equal to ((x1+x2)/2, (y1+Y2)/2) where (x1,y1) is one endpoint and (x2,y2) is the other endpoint. We know L (x2,y2), (-8,6) and midpoint (-5,10). Just up the equations for each coordinate and saw.

-5=(x1-8)/2 and 10=y1+6)/2 —> solve

-10=x1-8, so x1=-2. And 20=y1+6 so y1 =14

J point is (-2,14)
