Answer
No.
Work Step by Step
Step 1. Find the slope of the line formed by the first two points: $m_1=\frac{12-(-3)}{-5-(-1)}=-\frac{15}{4}$
Step 2. Find the slope of the line formed by the last two points: $m_2=\frac{12-(-11)}{-5-(1)}=-\frac{23}{6}$
Step 3. They have the different slopes, thus the three points are not collinear.
