Looks like they might be, but you need to do some calculations to verify.
Calculate the equation of a line between each set of points.
First find the slopes.
m=%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29
m%5B1%5D=%286-2%29%2F%284-3%29=4%2F1=4
m%5B2%5D=%28-8-6%29%2F0-4=-14%2F-4=7%2F2
No, at least two slopes don't match. They are not collinear.
