Answer:
C
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (4, - 1) ← 2 points on the line
m = =
note that the line crosses the y-axis at (0, - 2) ⇒ c = - 2
y = x - 2 ← equation of line

Answer:
$56,000
Step-by-step explanation:
If x is the number of days that Refinery A is in operation, and y is the number of days that Refinery B is in operation, then:
200x + 100y ≥ 800
300x + 100y ≥ 900
200x + 200y ≥ 1000
The total cost is:
C = 12,000x + 10,000y
x and y must be integers. Possible combinations are:
x = 0, y = 9
x = 1, y = 6
x = 2, y = 4
x = 3, y = 2
x = 4, y = 1
x = 5, y = 0
The costs of these combinations are:
The minimum cost is $56,000.
