Sample Response: A trend line shows the relationship between the two variables in the scatterplot. It can be used to predict based on the relationship, but it cannot be expected to produce exact figures.
vans = v, buses = b, students = s
8v + 8b =312s ...eqn 1
9v + 4b = 196s ...eqn 2
divide eqn 1 by 2
4v + 4b = 156s ...eqn 3
eqn 2 - eqn 3
5v = 40s
v = 8s
subst v = 8s in eqn 2
72s + 4b = 196 s
b = 31s
answer
each van holds 8 students and each bus holds 31 students
