Concept Check Graph the points on a coordinate system and identify the quadrant or axis for each point. (3, 2)

검증된 단계별 안내

Start by understanding the coordinate system: the horizontal axis is the x-axis and the vertical axis is the y-axis.

Locate the point (3, 2) by moving 3 units to the right along the x-axis because the x-coordinate is positive 3.

From that position, move 2 units up along the y-axis because the y-coordinate is positive 2.

Mark the point where these two movements intersect on the graph.

Identify the quadrant: since both x and y are positive, the point (3, 2) lies in Quadrant I.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Cartesian Coordinate System

The Cartesian coordinate system uses two perpendicular axes, the x-axis (horizontal) and y-axis (vertical), to locate points in a plane. Each point is represented by an ordered pair (x, y), where x indicates horizontal position and y indicates vertical position.

Plotting Points

Plotting a point involves moving x units along the x-axis and y units along the y-axis from the origin (0,0). For example, the point (3, 2) is found by moving 3 units right and 2 units up from the origin.

Quadrants and Axes Identification

The coordinate plane is divided into four quadrants based on the signs of x and y values: Quadrant I (+, +), Quadrant II (-, +), Quadrant III (-, -), and Quadrant IV (+, -). Points on the axes have either x=0 or y=0, indicating they lie on the x-axis or y-axis.
