Answer:

  p = (-1/5000)x +11

Step-by-step explanation:

We are given two points (x, p) as (5000, 10) and (15000, 8). Using the two-point form of the equation of a line, we can find the equation to be ...

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1 . . . . . 2-point form

  p = (8 -10)/(15000 -5000)(x -5000) +10

  p = -2/10000(x -5000) +10

  p = -x/5000 +11 . . . . . linear demand function
