Scatter Plots and Line of Best Fit

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables by displaying data points on a two-dimensional plane.

Front

What does the line of best fit represent in a scatter plot?

Back

The line of best fit is a straight line that best represents the data points in a scatter plot, indicating the trend of the data.

Front

How do you determine the slope of a line?

Back

The slope of a line is determined by the formula (change in y) / (change in x) between two points on the line.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that is significantly different from the other points in the scatter plot, often lying far away from the main cluster.

Front

What does a positive correlation in a scatter plot indicate?

Back

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

Front

What does a negative correlation in a scatter plot indicate?

Back

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

Front

What is the purpose of finding the intersection of two equations?

Back

Finding the intersection of two equations helps to determine the point where the two lines meet, which represents a common solution.

Front

How can you identify the solution to a system of equations graphically?

Back

The solution to a system of equations can be identified graphically by finding the point where the graphs of the equations intersect.

Front

What is the equation of a line in slope-intercept form?

Back

The equation of a line in slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept.

Front

What does it mean if two lines are parallel?

Back

If two lines are parallel, they have the same slope and will never intersect.
