the point P(-2,6) across reflected acress the line y=-x and then across the y-axis. What are the coordinates of the point after the reflections?
Added by Melissa C.
Step 1
To do this, we can use the formula for reflecting a point across a line y=mx+b: x' = (x + m*y - m*b) / (1 + m^2) y' = (m*x - y + b) / (1 + m^2) where (x', y') are the new coordinates, (x, y) are the original coordinates, and m and b are the slope and Show more…
