Front

What is the slope of a line?

Back

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

Front

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

Back

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

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where the change in x is zero.

Front

What is the y-intercept of a line?

Back

The y-intercept is the point where the line crosses the y-axis, represented as (0, b) in the equation y = mx + b.

Front

How do you identify if a set of points represents a function?

Back

A set of points represents a function if each x-value is paired with exactly one y-value.

Front

What is the definition of a function?

Back

A function is a relation that assigns exactly one output (y) for each input (x).

Front

What is the slope of the line represented by the equation y = -5x + 6?

Back

The slope is -5.

Front

What is the y-intercept of the graph of y = -5x + 6?

Back

The y-intercept is 6.

Front

How do you determine if a graph is a function using the vertical line test?

Back

If a vertical line intersects the graph at more than one point, the graph is not a function.

Front

What is the slope of the line through the points (-4, 5) and (-4, 2)?

Back

The slope is undefined.
