Exploring Linear Equations in Geometry

The video tutorial explains how to find the length of segment KL on a line segment JL with point K. Given the expressions for segments JK and KL in terms of x, and the total length of JL, the tutorial demonstrates setting up and solving an algebraic equation to find x. Once x is determined, it is used to calculate the length of KL.

What is the algebraic expression for the length of segment JK?

• 16x + 18

• 7x + 9

• 9x + 9

• 114
