Hi,
The cordinates of reflection image are (0,1)
Step-by-step explanation
First draw the cartesian plane with x vales ranging from 4 to -4 and y values ranging from 4 to -4
The draw the line x=-1 which is a straight line passing through point (-1,0), (-1,-3) and (-1,3)
Plot the point P(-2,1), where its reflection on the line x= -1 will be 1 unit to the right of the line. i.e the point will be on the y-axis
