No.

Work Step by Step

Step 1. Find the slope of the line formed by the first two points: $m_1=\frac{5-(3)}{2-(-5)}=\frac{2}{7}$ Step 2. Find the slope of the line formed by the last two points: $m_2=\frac{5-(4)}{2-(-1)}=\frac{1}{3}$ Step 3. They have the different slopes, thus the three points are not collinear.
