What is the slope-intercept form of a linear equation?

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of the dependent variable (y) with respect to the independent variable (x).

Front

How do you identify the y-intercept in the equation y = 5x + 20?

Back

The y-intercept is the value of y when x = 0. In this case, the y-intercept is 20.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is an outlier in a scatter plot?

Back

An outlier is a data point that differs significantly from other observations in the dataset.

Front

How can you determine the steepness of a line?

Back

The steepness of a line is determined by the absolute value of its slope; a larger absolute value indicates a steeper line.

Front

What does it mean if two variables have a positive correlation?

Back

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

Front

What is the equation of a line with a slope of 5 and a y-intercept of 20?

Back

The equation is y = 5x + 20.

Front

How do you find the coordinates of an outlier in a dataset?

Back

To find the coordinates of an outlier, look for points that are far removed from the general trend of the data.
