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

Back

The equation of a line in slope-intercept form is given by 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 of a line represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What is a y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of y when x = 0.

Front

How do you determine the line of best fit for a set of data points?

Back

The line of best fit is determined by using statistical methods such as least squares regression to minimize the distance between the data points and the line.

Front

What is the purpose of a line of best fit?

Back

The purpose of a line of best fit is to model the relationship between two variables and make predictions based on that relationship.

Front

What does it mean if the slope of a line is positive?

Back

If the slope of a line is positive, it means that as x increases, y also increases, indicating a direct relationship between the two variables.

Front

What does it mean if the slope of a line is negative?

Back

If the slope of a line is negative, it means that as x increases, y decreases, indicating an inverse relationship between the two variables.

Front

What is the significance of the coefficients in a linear equation?

Back

The coefficients in a linear equation represent the slope and the y-intercept, which define the line's steepness and position on the graph.

Front

How can you identify the slope from an equation of a line?

Back

In the equation y = mx + b, the slope is represented by the coefficient m.

Front

What is the formula for calculating the slope between two points (x1, y1) and (x2, y2)?

Back

The formula for calculating the slope (m) is m = (y2 - y1) / (x2 - x1).
