Question

gráficas y funciones marcar un punto en el plano de coordenadas usa el lápiz para marcar el punto (3, -1).

Explanation:

Step1: Understand coordinate system

In a Cartesian coordinate system, a point \((x, y)\) has \(x\)-coordinate (horizontal) and \(y\)-coordinate (vertical). For \((3, -1)\), \(x = 3\), \(y=-1\).

Step2: Locate \(x = 3\)

Move 3 units to the right along the \(x\)-axis (positive direction).

Step3: Locate \(y = -1\)

From \(x = 3\), move 1 unit down along the \(y\)-axis (negative direction) to mark the point.

Answer:

To mark the point \((3, -1)\):

1. Start at the origin \((0,0)\).
2. Move 3 units right along the \(x\)-axis (since \(x = 3\), positive \(x\)-direction).
3. From that \(x\)-position, move 1 unit down along the \(y\)-axis (since \(y=-1\), negative \(y\)-direction).
4. Mark the intersection of this horizontal (from \(x = 3\)) and vertical (from \(y=-1\)) movement.

(Visually, on the grid, find the column corresponding to \(x = 3\) and the row corresponding to \(y=-1\), then mark their intersection.)
