Question

find relationship between X and y if the points (x, y), (1, 2) and (7,0) are collinear.
plz solve this problem fast.
it's very urgent​

Answer 1

Answer:

Since the points are colinear ,

Therefore ,

ar = x (y" - y"') + x" ( y"' - y') + x"' ( y' - y"') = 0

x ( 2 - 0 ) + 1 ( 0 - y ) + 7 ( y - 2 ) = 0

2x - y + 7y - 14 = 0

2x + 6y - 14 = 0

x + 3y - 7 = 0

x + 3y = 7
