those points donot lie in same line because their slopes are not equal
slope of first 2 points=0
slope of next 2 points=3/10
hence they donot form a line

these points do not lie on the same straight line.you can do this by using the distance formula.conseider these points A,B,andC respectively.For them to be on the straight line AB+BC=AC which is not the case here.therefore they donot lie on the same line.
