Basic Algebra and Coordinate Geometry

The video tutorial covers practice problems from unit seven, lesson 13. It begins with plotting the elevation of a submarine on a coordinate plane, followed by identifying quadrants for temperature changes. The tutorial then explains how to describe height requirements for an amusement park ride using inequalities. Finally, it demonstrates solving equations to find unknown values.

What is the correct coordinate pair for a point at 0 and negative 567 on a coordinate plane?

• (-567, 0)

• (0, 567)

• (0, -567)

• (567, 0)

If the temperature at 9:00 a.m. is freezing, in which quadrant would this point be plotted?
