Question

what is the x - coordinate of point u? write your answer as an integer or decimal to the nearest 0.5.

Explanation:

Step1: Identify the x - coordinate of point U

Looking at the graph, the x - axis is horizontal. Point U is located at a position on the x - axis. From the grid, we can see that point U is at \(x=- 1\) (wait, no, let's re - check the axes. Wait, the x - axis: the origin is (0,0). The horizontal axis: let's see the labels. Wait, the vertical axis is y, horizontal is x. Wait, the point U: looking at the grid lines, the x - coordinate (horizontal) of point U. Let's see the grid: each square is 1 unit? Wait, no, maybe I misread. Wait, the x - axis: the positive x is to the right, negative to the left. Wait, the point U: let's look at the x - coordinate. Wait, the graph: the x - axis has labels 0,1,2,... on the right (positive) and - 1, - 2,... on the left (negative). Wait, no, maybe the axes are swapped? Wait, no, the standard is x horizontal, y vertical. Wait, the problem says "x - coordinate of point U". Let's look at the grid. The point U is at x=-1? Wait, no, wait the grid lines: let's see the x - axis (horizontal) values. Wait, the origin is (0,0). The point U: looking at the horizontal (x) position. Wait, maybe the x - axis is labeled with positive to the right, negative to the left. Wait, the point U is at x = - 1? No, wait, maybe I made a mistake. Wait, the grid: each square is 1 unit. Wait, the point U: let's check the x - coordinate. Wait, the x - axis (horizontal) values: the origin is 0. To the left of the origin (negative x) and right (positive x). Wait, the point U is at x=-1? No, wait, looking at the graph, the point U is at x=-1? Wait, no, maybe the x - axis is reversed? Wait, no, the arrow for x is to the right, so positive x is to the right. Wait, the point U: let's see the x - coordinate. Wait, the y - axis is vertical, with positive up. Wait, the point U is at (x,y)=(-1,1)? No, wait, the x - coordinate: let's count the grid lines. From the origin (0,0), moving left (negative x) by 1 unit, so x=-1. Wait, but maybe the grid is such that each square is 1 unit, so the x - coordinate of U is - 1.0 (to the nearest 0.5, it's - 1.0). Wait, no, maybe I misread. Wait, let's re - examine the graph. The point U is at x=-1 (since it's one unit to the left of the origin on the x - axis). So the x - coordinate of U is - 1.0.

Step2: Round to the nearest 0.5 (if needed)

Since - 1.0 is already a multiple of 0.5 (because \( - 1.0=2\times(- 0.5)\)), the nearest 0.5 is - 1.0.

Answer:

-1.0
