Answer: The cost of operation was reduced by 21.29%.
Step-by-step explanation:
Since we have given that
Cost of operation earlier = $21,840 per month
Cost of operation now = $17,190 per month
Difference between them is given by
$21,840 - $17,190
=$4,650
Percentage by which the cost of operation was reduced is given by
Hence, the cost of operation was reduced by 21.29%.

Answer:
2y = x + 2
Step-by-step explanation:
Looking at the graph, we can see from one point to the next (from right to left), the x-value rises by 2 and the y-value by 1;
From this we can work out the gradient between two points using the formula, i.e. the change/difference in y divided by the change/difference in x:
Joining the points gives a straight line, which means a constant gradient of ¹/₂
Use the line equation formula to get the function:
y - y₁ = m(x - x₁)
m = ¹/₂
x₁ = 0
y₁ = 1
y - 1 = ¹/₂.(x - 0)
y - 1 = ¹/₂.x
2y - 2 = x
2y = x + 2
