The coordinate of point J on the number line is -9

How to determine the coordinate of point J?

The given parameters are

JK = KL

K = 7

L = 23

The above means that:

K = 1/2 * (J + L)

So, we have

7 = 1/2 * (J + 23)

Multiply both sides by 2

14 = J + 23

Subtract 23 from both sides of the equation

J = -9

Hence, the coordinate of point J on the number line is -9
