The point (-7,4) is reflected over the line x=-3. then the resulting point is reflected over the line y=x. where is the point located after both reflections

  (4, 1)

Step-by-step explanation:

Since the first reflection is over the vertical line x=-3, the y-coordinate remains the same. The x-coordinate of A' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':

  (-3, 4) = (A +A')/2

  2(-3, 4) -A = A' = (-6-(-7), 8 -4) = (1, 4)

The reflection over the line y=x simply interchanges the two coordinate values:

  A'' = (4, 1)

The point (-7,4) upon reflection over the lines x = -3 and y = x would be at point; (4,1).

According to the question;

For the first reflection;

However, the x-coordinate of P' will make the point (-3, 4) on the line of reflection be the midpoint between A and A':

For the second reflection;

Ultimately, the point P'' = (4, 1)
