What is a line of best fit?

Back

A line of best fit is a straight line that best represents the data on a scatter plot. It shows the trend of the data points and can be used to make predictions.

Front

How do you determine the slope of a line from a graph?

Back

The slope of a line is determined by the rise over run, which is the change in the y-values divided by the change in the x-values between two points on the line.

Front

What does it mean if a distribution is symmetric?

Back

A symmetric distribution is one where the left side of the graph is a mirror image of the right side, indicating that the data is evenly distributed around the mean.

What is a quadratic function?

Back

Front

What is the hourly rate in the equation c = 25 + 3h?

Back

The hourly rate is 3, which represents the cost per hour for renting the carpet cleaner.

Front

What does a right-skewed distribution indicate?

Back

A right-skewed distribution indicates that the majority of the data points are concentrated on the left side, with a long tail extending to the right.

Front

What is the purpose of a dot plot?

Back

A dot plot is used to display the frequency of data points in a dataset, allowing for easy visualization of distribution and trends.

Front

How can you identify a quadratic function from a graph?

Back

A quadratic function can be identified by its U-shaped curve (parabola) on a graph, which opens either upwards or downwards.

Front

What is the meaning 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 0.

Front

What does it mean for a function to be linear?

Back

A linear function is a function that graphs to a straight line, characterized by a constant rate of change or slope.
