Slope Basics

Front

What is the definition of slope?

Back

Slope is a measure of the steepness or incline of a line, typically represented as the ratio of the vertical change to the horizontal change between two points on the line.

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, resulting in an upward trend from left to right.

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, resulting in a downward trend from left to right.

What is an undefined slope?

Back

An undefined slope occurs when a line is vertical, meaning there is no horizontal change (the denominator is zero), making the slope calculation impossible.

What is a zero slope?

Back

A zero slope occurs when a line is horizontal, indicating that there is no vertical change (the numerator is zero) as the x-values change.

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).
