The answer is A because using the point slope formula y-y1=m(x-x1) you get the answer choice A
Olivia applied the scale factor to the measurements of the model she saw. We need to know those in order to calculate the new ones.

Riley's age = r
Riley's brother's age = r/4
If Riley was 11 five years ago, Riley is currently 11 + 5 years old, or 16 years old.
Now we just need to use r/4 to find Riley's brother's age:
16 /4 = 4
Riley's brother is 4 years old.
Hope this helps!
