How do you find a 2 regression equation?

The Linear Regression Equation The equation has the form Y= a + bX, where Y is the dependent variable (that’s the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the slope of the line and a is the y-intercept.

What does the multiple regression equation tell you?

Multiple regression generally explains the relationship between multiple independent or predictor variables and one dependent or criterion variable. A dependent variable is modeled as a function of several independent variables with corresponding coefficients, along with the constant term.

How to do antilog on TI-84?

Antilog is basically a reverse function of Log. You can calculate it by pressing [Shift] key before pressing the log key. Where is the inverse button on a TI 84? The inverse function is located in the fifth row of the left column on the calculator. To enter the multiplicative inverse of a number, enter the number and press [x–1].

How do you find the equation of a regression line?

A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable. The slope of the line is b, and a is the intercept (the value of y when x = 0).
