# Regression Plane

Learn about the regression plane in multiple regression.

## We'll cover the following

Let’s now fit a regression model and get the regression table corresponding to the regression plane. To keep things brief in this lesson, we won’t consider an interaction model for the two numerical explanatory variables `income`

and `credit_limit`

. This isn’t like the interaction model we considered in the Interaction Model lesson, using the model formula `score ~ age * gender`

. We’ll only consider a model fit with a formula of the form `y ~ x1 + x2`

. Confusingly, however, because we now have a regression plane instead of multiple lines, the label “parallel slopes” doesn’t apply when we have two numerical explanatory variables. Just as we’ve done multiple times, the regression table for this model using our two-step process is in the code output below.
