Find a point on the line of reflection that creates a minimum distance. Make a conjecture about the coordinates of the point P(a, b) reflected across the line y x.Translation: (x, y) (x, y - 4) Reflection across the y-axis Find the scale factor of dilation if PQ is dilated to PQ such that line PQ 18 and line PQ 6. A scale will multiply/divide coordinates and this will. Identify the glide reflection rule to map ABC onto ABC in the given figure. The graph of y -2 x is the reflection across the x-axis of the graph of y 2 x. Reflections Date Period Graph the image of the figure using the transformation given. A scale is a non-rigid translation in that it does alter the shape and size of the graph of the function.
Determine the number of lines of symmetry. This middle school math video explains what the coordinate rules are for reflections on a coordinate grid, and it shows where these rules come from by lookin. Consequently for every 1 along the line has gone up 1.Describe the reflection by finding the line of reflection.Where should you park the car minimize the distance you both will have to walk? You need to go to the grocery store and your friend needs to go to the flower shop. Now we all know that the shortest distance between any two points is a straight line, but what would happen if you need to go to two different places?įor example, imagine you and your friend are traveling together in a car. And did you know that reflections are used to help us find minimum distances?
