Linear Regression Cost function in Machine Learning is "error" representation between actual value and model predictions. To minimize the error, we need to minimize the Linear Regression Cost ...

That is the the basic form of linear regression by hand. Note that there ARE other ways to do this - more complicated ways (assuming different types of distributions for the data).

We call this process linear regression. Of course, there are several ways to find a linear function to fit this data, but I will use python. Here is the data for the women with a linear function.
