Question

Quadrilateral IJKL with vertices I( 5,2 ), J( 9,5), K( 5,-2 ), and L( 2,-3 ) : Reflect in the line x=1. What are the coordinates of J’?

Answer 1

The Solution:

Given that the vertices of a quadrilateral are:

`I(5,2),J(9,5),K(5,-2)\text{ and L(2,-3)}`

We are required to find the coordinate of J' when J(9,5) is reflected in the line x=1.

The new x-coordinate will become:

`x=1-9=-8`

So, the required coordinate of J' is:

`(-8,5)`

Therefore, the correct answer is J'(-8,5)
