Which technique is often used for graph interpretation in this module?

The technique of slope calculations is fundamental in graph interpretation because it provides insights into the rate of change of a relationship represented in the graph. Specifically, the slope indicates how steeply one variable changes in relation to another, which is particularly useful in both linear and non-linear contexts. Understanding the slope helps in analyzing trends and making predictions based on the data represented.

For instance, if the graph represents a function, the slope at any given point can reveal whether that function is increasing or decreasing and at what rate. In applied contexts, like economics or physics, slope can indicate things like speed or growth rate, making it a crucial tool for interpretation.

While area under the curve calculations and integration techniques are valuable in certain scenarios, they typically relate to measuring total accumulation or area rather than rate of change. Point plotting strategies may assist with visual representation but don't inherently provide the quantitative analysis that slope calculations do.
