Graded Assignment: 4.4-4.6

Front

What is a dependent variable?

Back

A dependent variable is the variable that is measured or tested in an experiment, and it is affected by changes in the independent variable.

Front

In a scatter plot, what does the line of best fit represent?

Back

The line of best fit represents the trend in the data, showing the general direction that the data points follow.

Front

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

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of the dependent variable when the independent variable is zero.

Front

How do you interpret the equation y = mx + b?

Back

In this equation, m represents the slope, and b represents the y-intercept of the line.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two quantitative variables, with points representing individual data points.

Front

What does it mean if a scatter plot shows a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also tends to increase.

Front

What does it mean if a scatter plot shows a negative correlation?

Back

A negative correlation means that as one variable increases, the other variable tends to decrease.

Front

What is the purpose of using a line of best fit?

Back

The purpose of using a line of best fit is to make predictions based on the data and to summarize the relationship between the variables.

Front

How can you determine the slope from a graph?

Back

The slope can be determined by selecting two points on the line and calculating the change in y divided by the change in x.
