show which of the following group are collinear and which ones are not a) A(-3,-3) B(1,0) C(5,3)
b)K(3,-1) L(5,1) M(1,7)
a. I graphed the 3 points, and they
formed a straight line. Therefore, the
3 points are colinear.
b. Graph the 3 points. If they form a st. line, they are colinear.
If all 3 segments have equal slopes, the points are colinear also.
