# Worksheet: Locating Points on the Coordinate Plane

In this worksheet, we will practice finding the x- and y-coordinates of a point and locating a point on an xy-plane given its ordered pair.

**Q3: **

The following graph represents the relation between pressure and elevation, where the -coordinate is the elevation in kilometres and the -coordinate is the pressure in bars.

Which quadrant would contain a point that is 11 km below sea level under a pressure of 6 bars?

- Aquadrant III
- Bquadrant IV
- Cquadrant I
- Dquadrant II
