Answer 1

a. -400

Explanation:

got it correct!

Answer 2

Option A. (-400)

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 =
`(y_(2)-y_(1))/(x_(2)-x_(1))`

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

= -400

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

Option (A) will be the answer.
