What is the definition of slope in mathematics?

Back

Slope is the measure of the steepness or incline of a line, defined as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

How do you calculate the slope of a line given two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula: m = (y2 - y1) / (x2 - x1).

What does a slope of 1/2 indicate about a line?

Back

A slope of 1/2 indicates that for every 2 units of horizontal change, there is a 1 unit increase in vertical change.

What does it mean if the slope is described as 'undefined'?

Back

An undefined slope indicates that the line is vertical, meaning there is no horizontal change (run) to calculate the slope.
