View answer and explanation

Correct option: D

x-y+1=0

Option D (

x-y+1=0

) is correct because the equation of a line passing through two points

(x_1, y_1)

and

(x_2, y_2)

can be found using the determinant form or the two-point form, and substituting the given points yields the correct equation.
