Question

if the points( x, y),( 1, - 2) and( 3, - 4) are collinear then prove that x+y+1 = 0​

Answer 1

Answer:

Collinear Points are the points which lie on the same plane it means their difference will be equal because there are at equal distance from each other

Step-by-step explanation:

1-x-2-y=3-1-4+2

-x-y-1=2-2

-x-y-1= 0

-1(x+y+1)=0

x+y+1=0/-1

x+y+1=0

hence proved the result
