Final answer:
The slope of a straight line between two points can be calculated using various methods such as numerical integration, midpoint formula, difference quotient, and solving a system of linear equations.
Step-by-step explanation:
The slope of a straight line between two points can be calculated using the formula:
slope = (change in y) / (change in x)
To calculate the slope, you can use the following methods:
- Numerical methods for integration: This method involves finding the area under the curve between the two points and dividing it by the difference in x-values.
- Midpoint formula: This formula uses the coordinates of the two points to find the midpoints and then calculates the slope using the rise over run.
- Difference quotient: This method involves finding the difference in y-values and dividing it by the difference in x-values.
- Solving a system of linear equations: This method involves finding the equation of the line passing through the two points and determining the slope from the equation.
For example, if we have two points (4,000, 5,000) and (6,000, 7,000), we can calculate the slope using any of the above methods.
