Slope Calculator

What is an Online Slope Calculator?

An Online Slope Calculator is a digital tool that calculates the slope of a line given two points on that line. The slope of a line is defined as the change in the vertical direction (rise) over the change in the horizontal direction (run) between two points. The formula used is:

Where $(x_1, y_1)$ and $(x_2, y_2)$ are the coordinates of the two points.

How to Use an Online Slope Calculator?

1. Access the Tool: Open a web browser and go to an online slope calculator website or app.
2. Enter the Coordinates: Input the coordinates of the two points. These should be in the form of (x1, y1) and (x2, y2).
3. Click "Calculate" or "Find Slope": Press the button to calculate the slope of the line.
4. View the Result: The slope value will appear on the screen, showing the rate of change between the two points.
5. Repeat or Adjust (if needed): Modify the coordinates for new calculations if you need to calculate the slope for different points.

Frequently Asked Questions-

1. What is the slope of a horizontal line?
   The slope of a horizontal line is 0 because there is no vertical change between two points on the line (rise = 0).

2. What is the slope of a vertical line?
   The slope of a vertical line is undefined because there is no horizontal change between two points on the line (run = 0), which makes the denominator zero.

3. Can the calculator handle negative slopes?
   Yes, the online slope calculator can handle negative slopes, indicating that the line is sloping downward from left to right.

4. What do I need to enter into the calculator?
   You need to input the coordinates of two distinct points on the line (x1, y1) and (x2, y2). Both x and y values are required for the calculation.

5. Can I use the calculator for non-linear graphs?
   No, the online slope calculator is designed for straight lines (linear graphs). For non-linear graphs, the slope can vary at different points and would require more advanced methods.
