Answer:
(-2,-3)
Step-by-step explanation:
Since there is a point P including coordinates (-1,5) and it is shown on a horizontal line i.e y =1
Now we have to compute the new coordinates of P
If a point is mirrored along a horizontal line, only vertical distance varies, however the horizontal distance is still the same, i.e. from y axis or x coordinate.
Therefore new x coordinate = -1
As P has 4 distance from the line y =1
Therefore P' will also contains a distance of 4 on the other side of y = 1
i.e. y coordinates could be
= 1 - 4
= -3
hence, the new coordinate is (-2,-3)
