Examples, solutions, videos, and worksheets to help grade 7 students learn how to use the slope formula to find the slope of a line passing through two points on the coordinate plane.
The slope formula is used to calculate the slope of a line that passes through two points in a two-dimensional Cartesian coordinate system (x, y). The slope (m) represents the rate at which the line rises or falls as you move from left to right. The formula for calculating the slope between two points (x1, y1) and (x2, y2) is as follows:
In this formula:
To calculate the slope between two points, you subtract the y-coordinates (vertical change) and divide it by the difference of the x-coordinates (horizontal change) between the two points.
Example:
Use the slope formula to find the slope of the line passing through these two points A(3, 4) and B(6, 8).
m = (8 - 4) / (6 - 3)
m = 4 / 3
So, the slope of the line passing through points A and B is 4/3.
