Question

A band is planning a concert at a local theater. The graph below shows the ticket sales per hour.

Answer 1

Answer:

Option A. (-400)

Step-by-step explanation:

Graph attached shows the sales of the concert tickets.

We choose the two points through which the given line is passing,

Let the two points are (0, 4000) and (10, 0)

Slope of a line = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

                        = $\frac{4000-0}{0-10}$

                        = -400

Therefore, slope of the line graphed has the slope = -400

Option (A) will be the answer.

Answer 2

Answer: A. -400 should be the answer
