What is the slope in a linear equation?

Back

The slope represents the rate of change of a line, indicating how much the y-value changes for a unit change in the x-value.

Front

What does the cost per game represent in a bowling scenario?

Back

The cost per game is the slope of the line representing the relationship between the number of games played and the total cost.

Front

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

Back

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

Front

What is a resting heart rate?

Back

The resting heart rate is the number of heartbeats per minute when a person is at rest.

Front

What does a rate of change indicate in a graph?

Back

The rate of change indicates how one quantity changes in relation to another, often represented as the slope of the line.

Front

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

Back

The y-intercept is the point where the line crosses the y-axis, representing the value of y when x is zero.

Front

What does a slope of 10/1 mean in practical terms?

Back

A slope of 10/1 means that for every 1 unit increase in x, y increases by 10 units.

Front

How can you interpret a slope of 0?

Back

A slope of 0 indicates a horizontal line, meaning there is no change in y as x changes.

Front

What is the formula for finding the slope between two points (4, 6) and (7, 10)?

Back

Slope = (10 - 6) / (7 - 4) = 4/3.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, showing an inverse relationship.
