A band is planning a concert at a local theater. The graph below shows the ticket sales per hour. What is the slope of the line shown in the graph?

A.
-400
B.
-250
C.
-2,000
D.
-1,500

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 =

                        =

                        = -400

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

Option (A) will be the answer.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
