Determine whether the three points are collinear.
-$$( - 1 , - 11 ) , ( - 8 , - 7 ) , ( - 5 , - 4 )$$

Question

Quizplus · Accepted Answer

To determine if three points are collinear, you can use the slope formula. The slope between the first two points $(-1, -11)$ and $(-8, -7)$ is $\frac{-7 - (-11)}{-8 - (-1)} = \frac{4}{-7}$. The slope between the second and third points $(-8, -7)$ and $(-5, -4)$ is $\frac{-4 - (-7)}{-5 - (-8)} = \frac{3}{3} = 1$. Since the slopes are not equal, the points are not collinear.
