Quizplus · Accepted Answer

To determine if three points are collinear, we can use the slope formula between each pair of points. If all slopes are equal, the points are collinear. The slope between the first two points is $\frac{-1 - 8}{-5 - (-9)} = \frac{-9}{4}$. The slope between the second and third points is $\frac{4 - (-1)}{0 - (-5)} = \frac{5}{5} = 1$. Since the slopes are not equal, the points are not collinear.
