In linear decay, in which direction does the graph generally go?
Answer and explanation
Correct answer: Downward from left to right
In linear decay, a quantity decreases by an equal amount over equal intervals. Hence, its graph is a straight line with a negative slope, moving downward from left to right. A line parallel to the x-axis represents a constant quantity, not decay. Exam tip: identify linear decrease by its negative slope.
