Final answer:
A calculator for finding the slope from two points calculates the rise over run between those points.
Step-by-step explanation:
The slope of a straight line between two points can be calculated by determining the rise over run between those points. To calculate the slope, designate one point as the starting point and the other point as the end point. Then, subtract the y-coordinate of the starting point from the y-coordinate of the end point to find the rise, and subtract the x-coordinate of the starting point from the x-coordinate of the end point to find the run. Finally, divide the rise by the run to get the slope.
For example, let's calculate the slope between the points A(4, 2) and B(8, 6). The rise is 6 - 2 = 4, and the run is 8 - 4 = 4. Therefore, the slope is 4/4 = 1.
