Question

Find the coordinate of the mirror image of A(1, 2) in the second quadrant.

Answer 1

Given that, the point is A(1,2)
A(1,2) is at a distance of 1 unit from x-axis and at a distance of 2 unit from y-axis.

$\therefore$ With respect to y-axis mirror image of A(1,2) is point(-1,2).
Which is at a distance of 1 unit from x-axis and at a distance of 2 unit from y-axis.
