Answer:

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 =
(y_2-y_1)/(x_2-x_1)

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

slope =
(0-4000)/(10-0)

$slope = (-4000)/(10)\\ slope = -400$

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