Explanation:

Step1: Recall Dilation Concept

Dilation with center at the origin \((0,0)\) scales each coordinate by a scale factor \(k\), so new coordinates \((x', y') = (k \cdot x, k \cdot y)\). But since the problem is about finding the scale factor (multiplying each coordinate by what), and typically if we assume a common dilation (maybe to reduce size, like to a simpler figure), but wait, the original points: A\((-8,8)\), B\((0,0)\), C\((-8,-8)\). Wait, maybe the dilation is to make the coordinates simpler, like scaling by \(\frac{1}{8}\) or \(\frac{1}{4}\)? Wait, no, maybe the problem is missing the scale factor description? Wait, no, maybe it's a standard dilation, but since the original points have coordinates with 8, maybe the scale factor is \(\frac{1}{8}\) or \(\frac{1}{4}\)? Wait, no, perhaps the problem is to find the scale factor, but maybe in the original problem (the image), the dilation is to make the triangle with smaller coordinates. Wait, but the user's problem shows "Multiply each coordinate by [ ]", and since the original points are A\((-8,8)\), B\((0,0)\), C\((-8,-8)\), maybe the scale factor is \(\frac{1}{8}\) to get A\((-1,1)\), B\((0,0)\), C\((-1,-1)\), but maybe it's \(\frac{1}{4}\)? Wait, no, maybe the problem is that the dilation center is \((0,0)\) (since B is at \((0,0)\)), and maybe the scale factor is \(\frac{1}{8}\)? Wait, no, perhaps the user missed the scale factor, but in typical problems, if the original triangle has vertices at \((-8,8)\), \((0,0)\), \((-8,-8)\), a common dilation is by \(\frac{1}{8}\) to get integer coordinates. But wait, maybe the problem is to find the scale factor, but since the problem is asking to "Multiply each coordinate by [ ]", and given the coordinates, maybe the scale factor is \(\frac{1}{8}\) or \(\frac{1}{4}\)? Wait, no, maybe the original problem (the image) has the triangle with those coordinates, and the dilation is to make it smaller, so scaling by \(\frac{1}{8}\) would make A\((-1,1)\), B\((0,0)\), C\((-1,-1)\). But maybe the scale factor is \(\frac{1}{8}\). Wait, but maybe I made a mistake. Wait, no, the problem is to find the number to multiply each coordinate by, so if we assume that the dilation is to get coordinates with absolute value 1 (simpler), then multiplying by \(\frac{1}{8}\) would work. So:

Step2: Determine Scale Factor

Given A\((-8,8)\), multiplying by \(\frac{1}{8}\) gives \((-1,1)\), B\((0,0)\) stays \((0,0)\), C\((-8,-8)\) becomes \((-1,-1)\), which is a simpler triangle. So the scale factor is \(\frac{1}{8}\). Wait, but maybe it's \(\frac{1}{4}\)? No, \(-8 \times \frac{1}{4} = -2\), \(8 \times \frac{1}{4} = 2\), which is also possible. But given the coordinates, the most probable is \(\frac{1}{8}\) to get to \((-1,1)\), etc. Wait, but maybe the problem is that the dilation is by a factor of \(\frac{1}{8}\). So the answer is \(\frac{1}{8}\)? Wait, no, maybe \(\frac{1}{4}\)? Wait, no, let's check: A\((-8,8)\) times \(\frac{1}{8}\) is \((-1,1)\), B\((0,0)\) times \(\frac{1}{8}\) is \((0,0)\), C\((-8,-8)\) times \(\frac{1}{8}\) is \((-1,-1)\). That makes a small triangle. So the scale factor is \(\frac{1}{8}\).

Answer:

\(\frac{1}{8}\)
