When a shape is reflected, it must be reflected across a line
See attachment for the graphs of JKL and its image
The given parameters are:
[tex]\mathbf{J = (3,-5)}[/tex]
[tex]\mathbf{K = (4,-1)}[/tex]
[tex]\mathbf{L = (0,-3)}[/tex]
The rule of reflection across line [tex]\mathbf{y = -3}[/tex] is:
[tex]\mathbf{(x,y) \to (x,-y - 6)}[/tex]
So, we have:
[tex]\mathbf{J' = (3,5 - 6) = (3,-1)}[/tex]
[tex]\mathbf{K' = (4,1 - 6) = (4,-5)}[/tex]
[tex]\mathbf{L' = (0,3 - 6) = (0,-3)}[/tex]
This means that, the coordinates of the image of JKL are:
[tex]\mathbf{J' = (3,-1)}[/tex]
[tex]\mathbf{K' = (4,-5)}[/tex]
[tex]\mathbf{L' = (0,-3)}[/tex]
