Question

Find the coordinates of the vertices of the given points below after a dilation of 3.5 about the origin.

Answer 1

Q'(-3.5,-3.5), R'(0,3.5), S'(3.5,0)

Explanation:

To find the coordinates of the image points after the dilation of 3.5 about the origin, we just multiply the x and y-coordinates of each vertex by 3.5 as follows:

`Q(-1,-1)= > Q'(-1*3.5,-1*3.5)=Q'(-3.5,-3.5)`

`R(0,1)= > R'(0*3.5,1*3.5)=R'(0,3.5)`

`S(1,0)= > S'(1*3.5,0*3.5)=S'(3.5,0)`
