For the answers A and B, we have to calculate the slope of this line.
Given two points (x₁,y₁) and (x₂,y₂), the slope of the line that passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
We can see two points clearly in this line:
(4,3)
(12,9)
if we compute the slope of the line that passes through these points,we find the next value for the slope:
m=(9-3)/(12-4)=6/8=3/4=0.75
Therefore, the answer A will be the correct answer;
For the answers C and D, you have to do the next question;
What do it mean a slope with a value 3/4??
slope=3/4=3 boxes/4 minutes.
It means that 3 boxes are filed every 4 minutes.
Therefore, the answer D will be correct too.
Answer: A and D are the correct answers.
