If K is the midpoint of JL , JK = MN, LM = 3JK and JN = 78, find LN

A. 42

JN, which is the whole line, equals 78. We learned that JK, KL, and MN are all equal, and that LM equals three points.

So, there are 6 parts to the line in total. Dividing 78 by 6 gives you 13 for a sixth of the line.

Now, to find LN all you have to do is know that LM is 13 times three. And just add one more 13 from MN.

13 x 4 = 42 as your answer. I hope you were able to follow my explanation lol

There is no graph but what i can say is that 1 is the slope and that -2 is the y- intercept
