Find the ratio in which the line segment joining the points (-3, 8) and (5, - 9) is divided by (0, 2).
The case is not possible
Let the ratio in which the line segment joining (-3, 8) and (5, - 9) is divided by (0, 2) be k : 1.
Therefore, 0=5k−3k+1
5k−3=0
k=35
Therefore, the required ratio is 3:5.
This was obtained using the x-coordinate as the reference.
If we now use the y-coordinate, we have
2=−9k+8k+1
2k+2=−9k+8
11k=6
k=611
Now we get two different ratios, one when we use the formula for x-coordinate, and the other when we use the formula for the y-coordinate.
This means that the points in question are not collinear.
Hence, the point (0, 2) cannot divide the join of (-3, 8) and (5, - 9).
