Answer:
the transformation is dilation
He didn’t multiply by 4 first
Find and compare the unit rates of decline:
Run "a":
-60 yds
------------- = -0.171 yds per yd
350 yds
Run b
115 yds
------------- = -0.290 yds per yd
550 yds
Slope (b) is the steeper.
Simplifying, Dividing, and Evaluating....the answer is 2.
Now, if you want to Find the Domain (unlikely, but still possible), that's another answer.
