FAQs on Slope of a line Video Lecture - Mathematics (Maths) Class 11 - Commerce

1. What is the slope of a line?
Ans. The slope of a line is a measure of how steep or flat the line is. It represents the rate of change between the vertical and horizontal distances of two points on the line.
2. How do you calculate the slope of a line?
Ans. The slope of a line can be calculated by dividing the change in the vertical distance (y) by the change in the horizontal distance (x) between two points on the line. It is expressed as the ratio of rise (change in y) to run (change in x), i.e., slope = (y2 - y1) / (x2 - x1).
3. What does a positive slope indicate?
Ans. A positive slope indicates that the line is moving upward from left to right. It means that as the x-coordinate increases, the y-coordinate also increases, resulting in an upward trend.
4. What does a negative slope indicate?
Ans. A negative slope indicates that the line is moving downward from left to right. It means that as the x-coordinate increases, the y-coordinate decreases, resulting in a downward trend.
5. What does a zero slope indicate?
Ans. A zero slope indicates a horizontal line. It means that the line is neither moving upward nor downward. In this case, the y-coordinate remains constant regardless of changes in the x-coordinate.
