# Y Hat Equals A Plus Bx

### We could also write that weight is -31686697height.

Y hat equals a plus bx. Y equals a plus b-x. OK so its still linear. The form of the question gives it to us very directly.

Linear equations A linear equation is an equation of the form ax b y slope-intercept form where x y are the independent and dependent variable respectively and a b are some predetermined. Ln y-hat a bx. It is customary to talk about the regression of Y on X hence the regression of weight on height in our example.

X is the value where the line intercepts the x axis. B is the point value of where the line intercepts the y axis called the y intercept. Linear Regression and Correlation.

Linear Regression and Correlation. Linear Regression and Correlation. Ln y-hat a b ln x.

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. Y-hat a bx. Equation of a line.

The x-intercept is found by setting y 0 because that will give us. Y y y-hat. Linear Regression and Correlation.
