(30 points! ) 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.

(i need a written answer that describes the features that are needed to determine if the lines intersect. )

Both the equations must have 'Time passed after the game started' (t), as one of the key variables.

If (for a  value of t) the point  where they intersect be (), then, it does imply that  number of hot-dogs  were purchased when there was unit of time left in the football game.

Step-by-step explanation:

The linear function that represents the number of hot-dogs(x) purchased at a football game should be plotted against the variable 'Time passed after the game started' (t).

So, the equation will be ,

       x = a + bt ----------------(1) [where a ,b are constants to be found out]

The second linear function which represents the time left in the game(y) should also be plotted against 'Time passed after the game started'(t).

So the equation will be,

                   y = c + dt -------------(2) [where c ,d are constants to be found out]

If done so, if (for a  value of t) the point  where they intersect be (), then, it does imply that  number of hot-dogs  were purchased when there was unit of time left in the football game.
