The points (-20,r) and (-4,9) lie on a line with slope
Find the missing coordinate r.

hi! i think the answer is 1/2 : )

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.

4 inches will get you 10.16 centimeters, but you can either do 10.1 or round up to 10.2. good luck and hope this : )
