What does the slope of a line represent?

Back

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

What does it mean for a line to be increasing?

Back

A line is increasing if the slope is positive, meaning as x increases, y also increases.

Front

What does it mean for a line to be decreasing?

Back

A line is decreasing if the slope is negative, meaning as x increases, y decreases.

How can you graph a linear equation?

Back

To graph a linear equation, you can find the y-intercept, plot it on the graph, use the slope to find another point, and draw a straight line through the points.

What is the difference between a function and a relation?

Back

A function is a special type of relation where each input (x-value) has exactly one output (y-value).
