p = 6n. The equation that best represents many points n touchdowns are worth is p = 6n.
This is a problem of direct proportionality, given two variables X and Y, Y is (directly) proportional to X (X and Y vary directly, or X and Y are in direct variation) if there is a constant other than zero such that:
y = kx
A touchdown in football represents 6 points, if n is stands for the number of touchdowns, then
k = 6 is a constant that represents 6 points of a touchdown.
n is the number of touchdowns.
p is the total points from touchdowns.
p = 6n
