Given a line k is between J and L from J-K the line is 8x+11 and from K-L its 14x-1. So first youre going to have to solve for X
Since K is the midpoint both equations are equal to eachother so the first equation is
8x+11=14x-1
-6x+11=-1
-6x=-12
x=2
Now since we have x we can solve so youre going to put x into one of the equations. It doesnt matter which once cause they are both equal. So we can do 8x+11
8(2)+11
16+11
27
So now we have 27 we can add both together since 27=27
So you have JL=54 un
Use un if you dont have a distance
Hope this helps!!
