If the point p (2,-1 )is reflected across the y axis what are the coordinates of its reflection image

Step-by-step explanation:

The given point p ( 2, -1 ) lies in 4th quadrant and we have been asked to find the new coordinates of point p when reflected by y-axis.

If we consider y-axis as a mirror then image of point p will lie in third quadrant and coordinates will be in the form of ( -x, -y ).

So image of point p will be p'(-2, -1).

i think its 7.6

if so your welcome
