Front

What is the slope in the equation y=mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What is the y-intercept in the equation y=mx + b?

Back

The y-intercept (b) is the value of y when x=0.

Front

What defines a function in mathematics?

Back

A function is a relation where each input has exactly one output.

Front

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

Back

Check if any x-value is repeated; if it is, it's not a function.

Front

What is the slope of the line represented by the equation y=2x + 3?

Back

The slope is 2.

Front

What is the slope of the line represented by the equation y=0.5x - 2?

Back

The slope is 0.5.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

What is the significance of the y-intercept in a linear equation?

Back

It indicates where the line crosses the y-axis.

Front

Can a vertical line be considered a function?

Back

No, a vertical line is not a function because it has multiple y-values for a single x-value.
