Slope and a point on a line
The slope of a line is a measure of how steep or slanted the line is. It represents the rate at which the y-values change with respect to the x-values. The slope of a line can be calculated by finding the change in y divided by the change in x between two points on the line.
The formula for calculating the slope of a line passing through two points (x1, y1) and (x2, y2) is given by:
slope = (y2 - y1) / (x2 - x1)
If a point (x1, y1) lies on a line with a known slope m, then the equation of the line can be given by: y - y1 = m(x - x1)
Examples;
- Given two points on a line, (2, 4) and (6, 10), we can find the slope of the line:
