Question

4. Look at the figures below.How was each point of Polygon ABCDE shifted to get Polygon BCDE?A right I unit and down 4 unitsBright I unit and down 1 unitC. left 1 unit and up 4 unitsD. left I unit and up 1 unitTi

Answer 1

Given a polygon ABCDE with the coordinates

`A(-7,2),B(-8,4),C(-6,5),D(-5,6),E(-5,3)`

The image of the polygon has vertices A'B'C'D'E' with coordinates

`A^(\prime)(-6,-2),B^(\prime)(-7,0),C^(\prime)(-5,1),D^(\prime)(-4,2),E^(\prime)(-4,-1)`

The transformation rule as observed from the image is

`(x,y)\Rightarrow(x+1,y-4)`

Hence, the polygon has been shifted to the right by 1 unit and down by 4 units

Option A is the right answer
