Question

which point has coordinates (-2, -2 1/2)?

Explanation:

Step1: Understand coordinate meaning

In a coordinate pair $(x,y)$, $x = - 2$ means moving 2 units to the left of the y - axis and $y=-2\frac{1}{2}=-\frac{5}{2}$ means moving 2.5 units down from the x - axis.

Step2: Locate point on graph

Looking at the graph, point Z has an x - coordinate of - 2 and a y - coordinate of approximately - 2.5.

Answer:

Z
