What does the slope of a line represent in a linear function?

Back

The slope of a line represents the rate of change of the dependent variable (y) with respect to the independent variable (x). It indicates how much y changes for a unit change in x.

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x is 0. It is the point where the line crosses the y-axis.

What is the difference between a dependent and an independent variable?

Back

The independent variable is the variable that is changed or controlled in an experiment, while the dependent variable is the variable that is measured or affected.

How can you represent a situation with a linear equation?

Back

By identifying the relationship between two quantities, determining the fixed and variable costs, and forming an equation that describes that relationship.

How do you interpret the slope in a real-world context?

Back

The slope indicates how much the dependent variable changes for each unit increase in the independent variable, providing insight into the relationship between the two.

Front

What does it mean if a linear function has a negative slope?

Back

A negative slope indicates that as the independent variable increases, the dependent variable decreases, showing an inverse relationship.
