Graphing linear equations (y = mx + b), systems of equations, and finding slope and intercepts.
中心X/Y軸と象限番号付き
A Cartesian coordinate plane divides a 2-dimensional space into four quadrants via two perpendicular directed axes intersecting at the origin (0, 0). The horizontal line is the X-axis (abscissa) and the vertical line is the Y-axis (ordinate).
Q_I: (+x, +y); Q_II: (-x, +y); Q_III: (-x, -y); Q_IV: (+x, -y); Origin: (0, 0)Named after French mathematician and philosopher René Descartes (1596–1650), the Cartesian coordinate system bridged Euclidean geometry and elementary algebra, giving birth to analytic geometry and calculus.

Graphing linear equations (y = mx + b), systems of equations, and finding slope and intercepts.
Plotting reflections, rotations, translations, and dilations of geometric polygons across quadrants.
Graphing periodic waves with origin-centered symmetry across negative and positive domains.
Decomposing 2D force vectors into orthogonal components (Fx = F · cos(θ), Fy = F · sin(θ)).
The intersection of the two bold arrow-tipped lines represents the origin (0, 0).
Use the major line intervals (every 5 grid cells) to label milestones: 5, 10, 15 on positive axes and -5, -10 on negative axes.
Move horizontally along the X-axis to x, then vertically parallel to the Y-axis to y. Mark the point with a distinct dot.
Connect points with a continuous curve or line, extending with arrowheads to indicate infinite domains.
Primary X and Y axes are centered within 0.1 mm of the true sheet centroid.
