Question

which point has coordinates (2.5, -1.5)?

Explanation:

Step1: Recall coordinate system rules

In a coordinate plane, a point \((x, y)\) has \(x\)-coordinate (horizontal) and \(y\)-coordinate (vertical). For \((2.5, -1.5)\), \(x = 2.5\) (right of origin, between \(x = 2\) and \(x = 3\)) and \(y=-1.5\) (below origin, between \(y = -1\) and \(y = -2\)).

Step2: Analyze each point

• Point \(R\): Around \(x\approx2.5\), \(y\approx0\) (not \(-1.5\)).
• Point \(S\): \(x\approx2.5\), \(y\approx1.5\) (positive \(y\), wrong).
• Point \(T\): \(x\approx2.5\), \(y\approx -1.5\) (matches \(x = 2.5\), \(y=-1.5\)).
• Point \(U\): \(x\approx -1.5\), \(y\approx -2.5\) (wrong \(x\)).

Answer:

T
