The coordinates of another vertex on the figure is:
[tex]\boxed{(1,-3)}[/tex]
Explanation:
If a figure has a vertex at (-1,-3) and the figure has a symmetry about the y-axis, then the coordinates of another vertex on the figure is:
[tex]Point \ (1,3)[/tex]
This is so because the rule for reflecting any point [tex](x,y)[/tex] across the y-axis is the point [tex](-x,y)[/tex]. So you just need to multiply the x-coordinate of the original point by -1 in order to get the coordinate of another vertex.
