JK¯¯¯¯¯ is dilated by a scale factor of n with the origin as the center of dilation, resulting in the image J'K'¯¯¯¯¯¯. The slope of JK¯¯¯¯¯ is m. If the length of JK¯¯¯¯¯ is l, what is the length of J'K'¯¯¯¯¯¯?

m × n × l

(m + n) × l

m × l

n × l

@javierpratdesaba Do you know how this would be worked out? :)

javierpratdesaba · Answer

Ok. Which part of the question do you think would be useless in finding the length of J'K'?

anonymous · Answer

The slope, right? @javierpratdesaba

javierpratdesaba · Answer

Exactly. So letter m is useless. What answers can you eliminate that have the letter m?

anonymous · Answer

A,B AND C. :) Thank you so much! You are helping more than I can say. @javierpratdesaba
