Answer:

  C = 9x +2280

Step-by-step explanation:

The 2-point form of the equation for a line can be a place to start.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  C = (4800 -3000)/(280 -80)(x -80) +3000 . . . . . use given values

  C = 1800/200(x -80) +3000 . . . . simplify some

  C = 9x -720 +3000 . . . . eliminate parentheses

  C = 9x +2280

Answer: 18.7

Step-by-step explanation:

Find the lengths of AB, BC, and CA

AB = \sqrt{(4-(-1))^{2} + (-1-4)^{2} } = 5\sqrt{2} ≈ 7.1

BC = \sqrt{(0-(-1))^{2} + (-3-4)^{2} } = 5\sqrt{2} ≈ 7.1

CA = \sqrt{(0-4)^{2} + (-3-(-1))^{2} } = 2\sqrt{5} ≈ 4.5

7.1 + 7.1 + 4.5 = 18.7

y2 - y`1 / x2 - x1

7/2 - 11 / 4 - (-8)

-15/2  / 12

= -5/8

y = -5/8x + b

11 = -5/8(-8) + b
