The graph shows the relationship between time and the number of soda bottles a machine can
make. Use the points (2,40) and (4,80) to find the
number of soda bottles the machine can make
each minute.

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

false, it is 3

-35* 3 = -105
