First Quadrant
Understanding the origin
\[ (0, 0) \]
Identify that the origin has coordinates (0, 0).
Reading x-coordinate in first quadrant
\[ x = 3 \]
Read just the x-coordinate (horizontal position).
Reading y-coordinate in first quadrant
\[ y = 4 \]
Read just the y-coordinate (vertical position).
Writing coordinates in first quadrant
\[ (4, 1) \]
Write both coordinates in correct (x, y) format.
Identifying a point from coordinates
\[ \text{Which is } (3, 1)\text{?} \]
Match coordinates to labelled points.
Coordinates of points on the x-axis
\[ (3, 0) \]
Points on the x-axis have y-coordinate 0.
Coordinates of points on the y-axis
\[ (0, 2) \]
Points on the y-axis have x-coordinate 0.
Four Quadrants
Coordinates on the axes
\[ (-3, 0) \text{ or } (0, 2) \]
Read coordinates of points on the axes.
Reading coordinates with one negative
\[ (-2, 3) \]
Read coordinates in quadrant 2 or 4.
Reading coordinates with two negatives
\[ (-1, -2) \]
Read coordinates in quadrant 3 (both negative).
Identifying the quadrant from coordinates
\[ (-2, 3) \rightarrow \text{Q2} \]
Determine which quadrant a point lies in.
Identifying a point from coordinates
\[ (-2, 1) \rightarrow \text{?} \]
Identify which labelled point matches given coordinates.
Quadrant Properties
Signs of coordinates in each quadrant
\[ \text{Q2: } (-, +) \]
Know the sign patterns for each quadrant.
Comparing x and y values of points
\[ x \lessgtr y \text{?} \]
Compare the x and y coordinates of a point.
Points with equal x and y coordinates
\[ x = y \]
Identify points where x = y.
