Question

Which is the function rule that will transform a geometric figure by reflecting across the y-axis and

up 5 units?
O f(x,y)=(-x+5. y)
Of(x,y) = (x+5,-Y)
Of(x,y)=(x, -y+5)
Of(x,y) = (-x, y+5)

Answer 1

Explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).
