प्रश्न
A cat is located at the point(– 6, – 4) in xy plane. A bottle of milk is kept at (5, 11). The cat wish to consume the milk travelling through shortest possible distance. Find the equation of the path it needs to take its milk.
उत्तर
Equation of the line joining the point is
`(y - y_1)/(y_2 - y_1) = (x - x_1)/(x_2 - x_1)`
`(y + 4)/(11 + 4) = (x + 6)/(5 + 6)`
`(y + 4)/15 = (x + 6)/11`
15(x + 6) = 11(y + 4)
15x + 90 = 11y + 44
15x – 11y + 90 – 44 = 0
15x – 11y + 46 = 0
The equation of the path is 15x – 11y + 46 = 0
