Step-by-step explanation:
The gradient = change in y / change in x
When the x value increases by 1, the y value decreases by 2 so -2 / 1 = -2
The y intercept is 4, so it is +4
Answer:
538,650
Step-by-step explanation:
We must first find how many errors there will be if filed manually and if filed electronically
Manually: 2,700,000*20% or 2,700,000*.2
Answer: 540,000 errors
Electronically: 2,700,000*.05% or 2,700,000*.0005
Answer: 1,350 errors
We must then find the difference; 540,000-1,350=538,650
