abs%28matrix%283%2C3%2C1%2C0%2C-4%2C1%2C+-3%2C+-13%2C+1%2C2%2C2%29%29+=+0, so the three points are collinear.

Another solution is to calculate the slope values between the 2-nd and the 1-st point and between the 3-rd and the 2-nd points.

If the slope values are the same, then the points are collinear.
