Answer:
28 straight lines can be formed.
Step-by-step explanation:
Step 1: To Find the Straight lines formed on 8 non collinear points
Step 2: We know that the straight line has two points.
Step 3: That is, it has starting point and ending points
Step 4: Therefore according to permutation and combination we have
Number of lines = 8C2
Step 5: Expand the above combination value.
=8x7/2x1
=4x7
=28 lines
Step 6: Therefore 28 straight lines are formed from 8 non - collinear points on the X-Y plane.
