The slope of a line is a measure of its steepness or incline. It represents the change in the y-coordinate divided by the change in the x-coordinate between any two points on the line.
To find the slope of a line, you can use the slope formula, which is (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are any two points on the line. Alternatively, you can count the rise (vertical change) over the run (horizontal change) between two points on the line.
A positive slope indicates that the line is increasing from left to right. This means that as the x-coordinate increases, the y-coordinate also increases. In other words, the line is moving upwards.
A negative slope indicates that the line is decreasing from left to right. This means that as the x-coordinate increases, the y-coordinate decreases. In other words, the line is moving downwards.
Yes, the slope of a line can be zero. This indicates that the line is horizontal and has no incline. In this case, the y-coordinate remains the same regardless of the change in the x-coordinate.
