Unit 5 Lessons 1 - 4 Review

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'rise over run' (change in y over change in x).

Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, meaning the line falls from left to right.

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 is a zero slope?

Back

A zero slope occurs in horizontal lines where the change in y is zero, indicating no rise.

Front

What is an ordered pair?

Back

An ordered pair is a pair of numbers used to represent a point in a coordinate system, typically written as (x, y).

Front

What is a function?

Back

A function is a relation where each input (x-value) has exactly one output (y-value).

Front

How can you determine if a set of points represents a function?

Back

A set of points represents a function if no x-value is repeated with different y-values.

Front

What is the rate of change in a function?

Back

The rate of change is the ratio of the change in the output value to the change in the input value, often represented as slope.
