Step-by-step explanation:
Under a reflection in the y- axis
a point (x, y ) → (- x, y ) , then
J (1, 4 ) → J' (- 1, 4 )
K (1, 0 ) → K' (- 1, 0 )
L (4, 3 ) → L' (- 4, 3 )
Plot the points J', K', L' and connect them in order to obtain image
Given a point in coordinates form

, one can compute the cartesian form like this:

We have:

We get the cartesian form then:
Idk seriously i suck at math but i use photomath it is a really good app u should try it
The range of the data is 93
