multiple regression with continuous and binary regressors

How can I do a multiple regression if I have continuous and ordinal (binary) (eg. male and female) regressors.

Can I just add them like this lm(y~x1+x2+x3+x4, data=data)?

Depends on y, continuous, categorial, or binary?

y is continuous in my data

If the independent variables are binary, and especially of they are 0 and 1, then yes, just use the formula you shared.

See for example:

Then that should be the way to start
