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 or negative).

What is the significance of the slope in a linear equation?

Back

The slope indicates the steepness and direction of the line. A positive slope means the line rises from left to right, while a negative slope means it falls.

What does it mean if a line has a slope of 0?

Back

If a line has a slope of 0, it is horizontal, meaning there is no change in the y-value as the x-value changes.

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

Back

An undefined slope occurs in a vertical line, where the x-value does not change, leading to a division by zero in the slope formula.

How can you graph a linear equation?

Back

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

What is the relationship between the slopes of parallel lines?

Back

Parallel lines have the same slope but different y-intercepts. They never intersect.
