Multivariate linear regression (Part 1)

In this exercise, you will work with the blood pressure dataset (Source), and model blood_pressure as a function of weight and age.

100 XP

The data frame bloodpressure is in the workspace.

Define a formula that expresses blood_pressure explicitly as a function of age and weight. Assign the formula to the variable fmla and print it.
Use fmla to fit a linear model to predict blood_pressure from age and weight in the data set bloodpressure. Call the model bloodpressure_model.
Print the model and call summary() on it. Does blood pressure increase or decrease with age? With weight?
