The graph provided shows a straight line with a negative slope, meaning it decreases as it moves from left to right.

This is a linear decreasing graph, not exponential decay. Exponential decay refers to a curve that decreases rapidly at first and then levels out, not a straight line.

The correct answer should be:

D. Linear decreasing

Would you like more details or have any questions?

Here are 5 related questions to deepen your understanding:

1. How can you differentiate between linear and exponential graphs visually?
2. What is the general equation for a linear function?
3. How can you identify exponential decay on a graph?
4. What are some real-world examples of linear decreasing functions?
5. How does the slope of a line affect whether it's increasing or decreasing?

Tip: A straight line on a graph always represents a linear function, and the slope determines whether it's increasing or decreasing.
