What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is and the direction it goes (upward or downward).

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input (x-value) has exactly one output (y-value). In contrast, a relation can have multiple outputs for a single input.

Front

How do you determine if a relation is a function?

Back

To determine if a relation is a function, use the vertical line test: if a vertical line intersects the graph at more than one point, the relation is not a function.
