Answer 7

1. t = 32d
look at graph...when t = 5 , d = 160...lets check
5 = 32(160) ... no way is this correct

2. unit rate is : 160/5 = 32 (true)
3. constant of proportionality = k.....k = y/x, k = 160/5 = 32 (true)
4. true

Answer 8

2nd one..
It grows 7 ft in 10 yrs...unit rate is how many ft it grows per yr.
Make a proportion
7/10 = x/1 (7 ft to 10 yrs = x ft to 1 yr)
cross multiply
10x = 7
x = 7/10
x = 0.7 ft per yr.....I think thats how you do this...you might want a second opinion on this one
