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.

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

Step-by-step explanation:

abde or 1,2,4, 5 is the answer

step-by-step explanation:

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
