ANSWER

EXPLANATION
From the graph, the coordinates of Y are:

We want to find the image of this point after a dilation by a scale factor of -½ about the origin.
The rule for the dilation is :

To find the coordinates of Y', we plug the coordinates of Y.


The first choice is correct.
Answer:
The formula is C=5/9(F-32).
4miles ..............56 minutes
42miles .............x
x= (42*56)/4
x= 2352/4
x= 588
