Question

find a relation between x and y if the points (x,y),(1,2) and (7,0) are collinear

Answer 1

Area should be zero for it to be collinear so using determinant method
1/2| 1 2 |
| 7 0 |
| x y |
| 1 2 | = 0
| 1-14+ 7y -0+2x -y |=0
2x + 6y =+/- 13
Hope its helpful

Answer 2

Answer:

Area should be zero for it to be collinear so using determinant method

1/2| 1 2 |

| 7 0 |

| x y |

| 1 2 | = 0

| 1-14+ 7y -0+2x -y |=0

2x + 6y =+/- 13

Hope it helps uh!
