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).

Front

What does it mean if the slope is positive?

Back

If the slope is positive, the line rises from left to right, indicating that as x increases, y also increases.

Front

What does it mean if the slope is negative?

Back

If the slope is negative, the line falls from left to right, indicating that as x increases, y decreases.

How can you graph a linear equation?

Back

To graph a linear equation, you can plot the y-intercept on the y-axis, use the slope to find another point, and then 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).
