Reading coordinates
The first quadrant is the corner of a grid where two lines meet. The line going across is the x-axis, and the line going up is the y-axis. They meet at the origin, which is the point (0, 0).
A point is written as (x, y). The first number tells you how far to go across (right). The second number tells you how far to go up.
Key idea
Coordinates (x, y): go across first, then up. Across before up, just like reading!
Worked example
Where is the point (3, 2)? Start at the origin (0, 0). Go 3 steps across to the right, then 2 steps up. That spot is the point (3, 2).
Remember
- Always count from the origin (0, 0).
- First number = across; second number = up.
