A set of five solutions are prepared by delivering 10 mL of unknown sample and increasing

A set of five solutions are prepared by delivering 10 mL of unknown sample and increasing
volumes of standard (0, 5, 10, 15, and 20 mL) into 50-mL volumetric flasks. Analytical
reagents are then added and diluted to volume. The x-intercept is –3.90 mM. What is the
unknown concentration?

Unsure how to go about this one. I think it's a standard addition exercise, but the book doesn't provide many examples.
