Types of Slopes

Front

What is the definition of a slope?

Back

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

Front

What is an undefined slope?

Back

An undefined slope occurs in vertical lines where the change in x is zero, leading to division by zero.

Front

What letter is used to represent vertical lines with an undefined slope?

Back

x

Front

What is a zero slope?

Back

A zero slope occurs in horizontal lines where there is no vertical change, meaning the line is flat.

Front

What letter is used to represent horizontal lines with a zero slope?

Back

y

Front

How do you write the equation of a vertical line?

Back

The equation of a vertical line is written as x = a, where 'a' is a constant.

Front

How do you write the equation of a horizontal line?

Back

The equation of a horizontal line is written as y = b, where 'b' is a constant.

Front

What is the slope of a line that goes up from left to right?

Back

The slope is positive.

Front

What is the slope of a line that goes down from left to right?

Back

The slope is negative.

Front

What does a slope of 1 indicate?

Back

A slope of 1 indicates that for every unit increase in x, there is a corresponding unit increase in y.
