Slope of a line:
The slope of a line is a measure of how steep it is. It is defined as the ratio of the change in y to the change in x between any two points on the line. In other words, it tells you how much the y-coordinate changes relative to the x-coordinate change.
Angle between two lines:
The angle between two lines is the angle formed between their corresponding rays. Two lines are said to be perpendicular if the angle between them is 90°, while they are said to be parallel if the angle between them is 0°.
The slope of a line is equal to the negative reciprocal of the slope of another line that is perpendicular to it. For example, if two lines have slopes of 2 and 1/2, respectively, then they are perpendicular to each other.
Examples:
A line with a slope of 2 has a steeper slope than a line with a slope of 1/2.
Two lines are perpendicular if their slopes are negative reciprocals of each other.
The slope of a line passing through the points (1, 3) and (4, 9) is equal to 3/2
