If the ordered pair (-5, 2) was added to each set shown, which set would NOT be a function?
A Set 2
B Set 4
C Set 3
D Set 1

i think it is c, not positive though

step-by-step explanation:

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75
