To find an ordered pair that also lies on the line created by the points \((-4,5)\), \((4,1)\), and \((8,-1)\), we first need to determine the slope of the line. The slope between the first two points can be calculated as: \[ \text{slope} = \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 5}{4 - (-4)} = \frac{-4}{8} = -\frac{1}{2} \] Using the point-slope form equation of a line, we can take one of the points, say \((4,1)\): \[ y - 1 = -\frac{1}{2}(x - 4) \] This simplifies to: \[ y = -\frac{1}{2}x + 3 \] Now, we can pick a value for \(x\) and find the corresponding \(y\). If we choose \(x = 0\): \[ y = -\frac{1}{2}(0) + 3 = 3 \] Thus, the ordered pair \((0, 3)\) is also on the line!
