Answer:
Option a) A line joining points, does not describe the slope.
Explanation:
Slope of a line:
- Slope is calculated by finding the ratio of the vertical change to the horizontal change between two distinct points on a line.
- It is defined as the change in the y coordinate divided by the corresponding change in the x coordinate, between two distinct points on the line.
- Slope of a line is a number that describes both the direction and the steepness of the line.
- Slope gives the constant rate of change or a measure of change between two points.
Hence, from the given options slope is not a line segment joining two points but it is the change in the line segment between two points.
Hence, option a) A line joining points, does not describe the slope.
