Question

A linear function that represents the number of hot dogs purchased at a football game is compared to a different linear function that represents the time left in the
game. Describe the key features of the functions that are needed to determine if these lines intersect.

Answer 1

Answer:

Lines are the same if m1 = m2 and b1 = b2 (they intersect in infinitely many points)

If b1 ≠ b2 and m1 = m2 then lines are parallel and do not intersect

If m1≠ m2 then lines will intersect at one point
