Unit 5 Recap - New Year (BW)

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a function?

Back

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

Front

How do you determine if a set of values represents a function?

Back

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

Front

What is the slope of a line?

Back

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

Front

What is the slope of the line represented by the equation y = 4/3x - 1?

Back

The slope of the line is 4/3.

Front

How do you calculate the slope between two points?

Back

The slope (m) between two points (x1, y1) and (x2, y2) is calculated using the formula m = (y2 - y1) / (x2 - x1).

Front

What is the slope of the line through the points (-1,-9) and (5,-6)?

Back

The slope is 1/2.

Front

What does it mean if a table is 'not a function'?

Back

If a table is 'not a function', it means that at least one x-value is associated with more than one y-value.

Front

What is the y-intercept in the equation y = 4/3x - 1?

Back

The y-intercept is -1.

Front

What is the difference between a function and a relation?

Back

A function is a specific type of relation where each input has one output, while a relation can have multiple outputs for a single input.
