Question

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

Answer 1

Answer:

A. -400

Step-by-step explanation:

Slope of a line is defined as the change in the component of the y- axis to its x axis as shown;

slope = Δy/Δx = $\frac{y_2-y_1}{x_2-x_1}$

From the graph, y2 = 0, y1 = 4000, x2 = 10, x1 = 0

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

$slope = \frac{-4000}{10}\\ slope = -400$

The slope of the line is a negative slope and it is -400
