not proportional, but linear
y = 60x is proportional
y=60x+3 is not proportional, but is linear, with the same slope of m=60
George observes that for every increase of 1 in the value of x, there is an increase of 60 in the corresponding value of y. He claims that this means the relationship represented by the table is proportional. Is George correct, saying that this table represents a proportional relationship? Why or why not?
