Question

If a point P (–2, 1) is reflected across the line x = –1, what are the coordinates of its reflection image?

Answer 1

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
