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, showing the trend of the data points.

Front

How do you determine the equation of a line parallel to another line?

Back

To find a parallel line, use the same slope as the original line and a different y-intercept.

Front

What does the slope 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 formula for finding the greatest common factor (GCF) of two numbers?

Back

The GCF is found by identifying the largest number that divides both numbers without leaving a remainder.

Front

What is the difference between a linear equation and a linear inequality?

Back

A linear equation shows equality (e.g., y = mx + b), while a linear inequality shows a range of values (e.g., y < mx + b).

Front

What does the y-intercept represent 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

How can you interpret the coefficients in a linear equation?

Back

The coefficients indicate the amount of change in the dependent variable for a one-unit change in the independent variable.

Front

What is the significance of the constant term in a linear equation?

Back

The constant term represents the value of the dependent variable when the independent variable is zero.

Front

How do you graph a linear equation?

Back

To graph a linear equation, plot the y-intercept and use the slope to find another point, then draw a line through the points.

Front

What is a scatter plot?

Back

A scatter plot is a graph that shows the relationship between two variables using dots to represent data points.
