Question

On a coordinate plane ,the segment with endpoints (10,40) and (70,120) is dilated by a factor of 4/5,with the origin as the center of dilation. What is the length of the resulting segment ?

A-80

B-100

C-112

D-125

Answer 1

The length of the dilated line segment is 80 units.

What is dilation?

Dilation is the increase or decrease in the size of a figure or object.

The segment with endpoints (10,40) and (70,120) is dilated by a factor of 4/5 to get (8, 32) and (56, 96).

The distance between points (8, 32) and (56, 96) is:

$Distance = \sqrt{(96-32)^2+(56-8)^2} =80\ units$

The length of the dilated line segment is 80 units.
