Question

use the graph to the right. Find the vertices of the image of QRTW for a dilation with center (0,0) and a scale factor of 10

Answer 1

The coordinates of QRTW after dilation by factor 10 are (-20,30),(-30,10),(20,-10),(-20,40).

Given that coordinates of QRTW before dilation are (-2,3),(-3,1),(2,-1),(-2,4) and figure QRTW is dilated by factor 10.

We know that if a figure is dilated its area, increases. The new coordinates can be calculated as x*factor from which it is dilated.

Coordinates are the points on the graph surface.

In our figure Q(-2,3), R(-3,1), S(2,-1), T (-2,4).

We have to just multiply each value with 10 to get the new coordinates of QRTW after dilation.

Q after dilation=(-2*10,3*10)=(-20,30)

R after dilation=(-3*10,1*10)=(-30,10)

S after dilation=(2*10,-1*10)=(20,-10)

T after dilation=(-2*10,4*10)=(-20,40)

Hence the vertices of the image QRTW after dilation are (-20,30),(-30,10),(20,-10),(-20,40).
