EOC Review (Literal/ROC/Linear Regression)

Front

What is the formula to solve for F in the equation S = 3F - 24?

Back

F = (S + 24)/3

Front

How do you determine the rate of change from a graph?

Back

The rate of change is calculated as the change in the y-values divided by the change in the x-values.

Front

What is the linear regression equation for a set of data points?

Back

The linear regression equation is in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

Solve for a in the equation a = pw. What is the rearranged formula?

Back

a = w/p

Front

How do you compare rates of change between two companies?

Back

Calculate the rate of change for each company and compare the values.

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of the dependent variable with respect to the independent variable.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x = 0 in the equation y = mx + b.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the significance of a negative slope in a linear regression?

Back

A negative slope indicates that as the independent variable increases, the dependent variable decreases.

Front

What does it mean if the rate of change is constant?

Back

A constant rate of change indicates a linear relationship between the variables.
