Linear Regression in Data Science

With graduation season just around the corner, I've had a few family members ask how often they would use the information they learned over the years. One cousin, in particular, was not a huge fan of math. However, he built his gaming PC and otherwise enjoys learning about computer hardware. At one point it was mentioned that computers will do all the necessary math, so why memorize formulas? While I saw his perspective to a degree, math is a building block to learning more about computers especially, and being able to verify results never hurt as a programmer. That train thought brought me back to Algebra 1, where I remember learning about graphs and modeling methods such as Linear Regression.
