Lesson 8: Ordered Pairs in All Four Quadrants6.NOS.7

I can…

I can plot ordered pairs in all four quadrants of the coordinate plane.

Key words

• Ordered Pairs in All Four Quadrants — Plot (x, y) points in all four parts of the grid.
• Quadrant — One of the four parts of a coordinate grid.
• Negative coordinate — A number less than zero. It means left or below the center.
• Reflection — A flip of a shape across a line.
• Axis — One of the two number lines that mark a graph.
• Integer — A whole number or its opposite, like 2 and −2.

Steps

1. I will plot (-3, -4). I start at the origin (0, 0).
2. The x is -3, which is negative, so I move 3 units to the LEFT.
3. The y is -4, which is negative, so I move 4 units DOWN. I place my dot.
4. Both coordinates are negative, so the point is in Quadrant III.

Try it

A point has a negative x-coordinate and a positive y-coordinate. Which quadrant is it in?

Check your answer

Quadrant II

Quadrant II is where x is negative and y is positive. This means the point is left of the origin and above the origin.
