What is the point of a minor?

The image of point (10,-14) under a reflection in point P is (-20,-20). What is the image of point (18,-14) un?

• Just need to know how to solve for image of point?!?! Step by step or something!?!?! Thank you!!!!!!!! The image of point (10,-14) under a reflection in point P is (-20,-20). What is the image of point (18,-14) under the same translation?

• Answer:

  For a reflection through the point (x,y), the conditions required are: 10 -x = (-20 - x) = x - (-20) and -14 -y = - (20 -y) = y - 20. This makes the x distance from the reflection point equal to minus the x distance from the reflection point (distance itself is always positive and equal to the absolute value of any difference between coordinates). The same is true for the y distances: the sign must reverse. In this case, from the equation for x: 2x = 10 - 20 and x = -5. From the equation with y in it: 2y = -14 + 20 = 6 and y = 3. From the above explanation, you should be able to find the same reflection "transformation" (or "operation") for the point (18, -14) using the reflection point found above. Don't use the word "translation" to describe such reflections, as that word means something entirely different from reflection operations. .
