Question

which point has coordinates (2.5, -0.5)?

Explanation:

Step1: Understand the coordinate system

In a coordinate system, a point is represented as \((x,y)\), where \(x\) is the horizontal (abscissa) and \(y\) is the vertical (ordinate) value.

Step2: Analyze the \(x\) - coordinate

For the point \((2.5,-0.5)\), the \(x\) - coordinate \(x = 2.5\). Looking at the graph, we move 2.5 units to the right of the \(y\) - axis.

Step3: Analyze the \(y\) - coordinate

The \(y\) - coordinate \(y=-0.5\). So from the \(x = 2.5\) line, we move 0.5 units down (since \(y=-0.5<0\)).

Step4: Identify the point

By following the \(x = 2.5\) (right - hand side of the \(y\) - axis) and \(y=-0.5\) (below the \(x\) - axis) directions on the graph, we can see that the point \(W\) has coordinates \((2.5,-0.5)\).

Answer:

W
