SAT Subject Test in Math I

The SAT Subject Test in Math I assesses students' understanding of fundamental mathematical concepts and skills.

Advanced Topics

Coordinate Geometry

Placing Math on a Map

Coordinate geometry combines algebra and geometry by plotting points, lines, and shapes on a plane.

The Coordinate Plane

Every point is represented by an (x, y) pair. You can find the distance between two points or the midpoint of a segment.

Equations of Lines

Linear equations describe straight lines. The slope formula helps determine how steep a line is.

Why It’s Useful

From video game graphics to city planning, coordinate geometry is everywhere!

Watch Out

  • Mixing up x and y coordinates
  • Forgetting to use the correct formula for distance or midpoint

Examples

  • Determining the shortest route between two locations on a map.

  • Graphing the path of a moving object in physics.

In a Nutshell

Coordinate geometry lets us describe and analyze geometric shapes using algebra.
