Question

what is the x - coordinate of point a?

Explanation:

Step1: Understand coordinate system

In a coordinate system, points are represented as \((x,y)\) where \(x\) is the horizontal (x - axis) coordinate and \(y\) is the vertical (y - axis) coordinate.

Step2: Locate point \(A\) on x - axis

Looking at the graph, for point \(A\), we move along the x - axis. Each grid square represents 1 unit. Counting the units from the origin (0) along the x - axis to the column where point \(A\) is located.
