Question

1. which of the following coordinates are not correctly named based on the image?

(6,-2)
(4,2)
all of the coordinates are correct
(-2,0)

Explanation:

Step1: Analyze each coordinate

- For \((-2,0)\): On the graph, the point is at \(x = -2\), \(y = 0\), so this is correct.
- For \((4,2)\): The point is at \(x = 4\), \(y = 2\), which matches the graph, so correct.
- For \((6,-2)\): Looking at the graph, the third point (the one labeled \((6,-2)\) in the option) actually has a positive \(y\)-coordinate? Wait, no, let's check the grid. Wait, the graph's third point: let's see the grid lines. Wait, the point labeled \((6,-2)\) in the option—wait, the graph shows a point at \(x = 6\)? Wait, no, the x - axis: the grid lines. Wait, the point that is supposed to be \((6,-2)\) – wait, looking at the graph, the third vertex (the bottom one) – let's check the coordinates. Wait, the x - coordinate: the vertical lines. Wait, maybe I misread. Wait, the graph: the left point is \((-2,0)\), the middle - right is \((4,2)\), and the bottom point: let's check its \(x\) and \(y\). Wait, the bottom point: looking at the grid, the \(x\)-coordinate: let's count the grid squares. Wait, the bottom point: if we look at the \(x\)-axis, the lines are at - 4, - 2, 0, 2, 4, 6? Wait, no, the graph's \(x\)-axis: the leftmost vertical line is - 4, then - 2, then 0, then 2, 4, 6. The bottom point: its \(x\)-coordinate – wait, maybe the bottom point is at \(x = - 6\)? Wait, no, the label in the graph is \((6,-2)\)? Wait, no, the graph's bottom point is labeled \((6,-2)\)? Wait, no, the user's graph: the three points are \((-2,0)\), \((4,2)\), and \((6,-2)\)? Wait, no, maybe the bottom point is at \(x=-6\)? Wait, no, the option is \((6,-2)\). Wait, maybe the mistake is that the \(x\)-coordinate is not 6. Wait, let's re - examine. The graph: the left point \((-2,0)\), the middle point \((4,2)\), and the bottom point: let's check the \(x\)-value. If we look at the horizontal (x - axis) grid lines, the bottom point is to the left of the \(y\)-axis? Wait, no, the graph shows a triangle. Wait, maybe the bottom point has \(x=-6\) instead of \(x = 6\)? Wait, the option \((6,-2)\) – the \(x\)-coordinate is 6, but on the graph, the bottom point is at \(x=-6\)? Wait, no, the user's graph: the bottom point is labeled \((6,-2)\) in the option, but in the graph, the bottom point's \(x\)-coordinate is negative? Wait, no, the graph's bottom point: let's check the \(x\)-axis. The vertical lines: from left to right, - 4, - 2, 0, 2, 4, 6. The bottom point: if we look at the \(x\)-coordinate, it's at - 6? Wait, no, the label in the graph is \((6,-2)\), but that's incorrect. Wait, maybe the bottom point is at \(x=-6\), \(y = - 2\)? But the option is \((6,-2)\), which has a positive \(x\)-coordinate, while the graph's bottom point should have a negative \(x\)-coordinate? Wait, no, maybe I made a mistake. Wait, the problem is "which of the following coordinates are not correctly named". So among the options, \((6,-2)\) is incorrect because the bottom point's \(x\)-coordinate is not 6 (it should be - 6, maybe? Or the \(y\)-coordinate is wrong). Wait, alternatively, maybe the bottom point has a positive \(y\)-coordinate? No, the bottom point is below the \(x\)-axis, so \(y\) is negative. But the \(x\)-coordinate: let's check the graph again. The left point is \((-2,0)\), the middle point \((4,2)\), and the bottom point: looking at the graph, the bottom point is at \(x=-6\), \(y=-2\)? But the option is \((6,-2)\), so the \(x\)-coordinate is wrong (6 instead of - 6). So \((6,-2)\) is incorrect. And the option "All of the coordinates are correct" is wrong because \((6,-2)\) is incorrect. Wait, no, the options are: A. \((6,-2)\), B. \((4,2)\), C. All of the coordinates are correct, D. \((-2,0)\). Wait, the user's options: the first option is \((6,-2)\), second \((4,2)\), third "All...", fourth \((-2,0)\). So we need to find which is not correct. So \((6,-2)\) is not correctly named (because the \(x\)-coordinate should be - 6, or maybe the \(y\)-coordinate? Wait, no, the graph's bottom point: let's check the coordinates again. Wait, the graph: the left point is \((-2,0)\) (correct, \(x=-2\), \(y = 0\)). The middle point \((4,2)\) (correct, \(x = 4\), \(y = 2\)). The bottom point: let's count the grid squares. From the \(y\)-axis (x = 0), moving left or right. Wait, the bottom point: if we look at the \(x\)-coordinate, it's 6 units to the left of the \(y\)-axis? No, 6 units to the right would be \(x = 6\), but the triangle is on the left side? Wait, no, the triangle has vertices at \((-2,0)\), \((4,2)\), and \((6,-2)\) – but that would make a triangle that is spread out, but maybe the bottom point is at \(x=-6\) instead of \(x = 6\). So the coordinate \((6,-2)\) is incorrect.

Step2: Conclusion

So among the options, \((6,-2)\) is not correctly named.

Answer:

A. \((6,-2)\)
