NEW Unit 5 CW Test Review: Linear Functions

Front

What is a linear function?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is and the direction it goes (positive or negative).

Front

How do you calculate the slope between two points?

Back

Front

What is the y-intercept of a linear function?

Back

Front

What does it mean for a line to be steeper?

Back

A steeper line has a greater absolute value of slope. This means that for a given change in x, the change in y is larger compared to a less steep line.

Front

How does shifting a line up affect its equation?

Back

Front

What is the standard form of a linear equation?

Back

Front

How do you identify parallel lines in terms of slope?

Back

Front

What is the difference between a positive and negative slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant. A negative slope indicates that as x increases, y decreases, resulting in a downward slant.

Front

How can you determine if a function is linear from a table of values?

Back

A function is linear if the differences between consecutive y-values divided by the differences between consecutive x-values are constant.
