3.2 FORMATIVE ASSESSMENT: Linear Functions

Front

What is the y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, b) where b is the value of y.

Front

Is the function represented by the table linear or nonlinear?

Back

A linear function has a constant rate of change and can be represented by a straight line on a graph.

Front

What is the slope?

Back

The slope of a line measures its steepness and direction, calculated as the change in y over the change in x (rise/run).

Front

Slope is another word for:

Back

Rate of Change.

Front

What is the y-intercept?

Back

The y-intercept is the value of y when x is 0, represented as (0, b).

Front

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

Back

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

Front

What does a positive slope indicate?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.
