Given data:
The given coordinate of JINX.
(a)
The expression for the coordinate after reflection over y-axis is,
The coordinate of J'I'N'X' is,
Thus, the coordinate of J' is (1, 13), I' is (-8, 10), N' is (-3, 8) and X' is (6, 11).
(b)
The expression for the coordinate of J''I''N''X'' is,
Thus, the coordinate of J'' is (-7, 6), I' is (-16, 3), N'' is (-11, 1), and X'' is (-2, 4).
