Front

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 (positive slope means the line rises, negative slope means it falls).

Front

How do you graph a linear equation?

Back

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

Front

What does it mean if a line has a slope of zero?

Back

A line with a slope of zero is horizontal, indicating that the y-value does not change as the x-value changes.

Front

What does it mean if a line has an undefined slope?

Back

A line with an undefined slope is vertical, indicating that the x-value does not change as the y-value changes.

Front

What is the standard form of a linear equation?

Back

Front

How can you determine if two lines are parallel?

Back

Two lines are parallel if they have the same slope but different y-intercepts.
