Question

An elephant standing at the junction of two straight roads represented by the equations x−y+2=0 and y−1=0 wants to reach another road whose equation is x−y−3=0. If the elephant can move in any direction and wants to cover the shortest distance to its destination road, then the equation of the path that the elephant should follow is:

Answer 1

Answer:

x+y=0

Step-by-step explanation:

Two roads intersect at (-1,1) & slope of line x-y+3=0 is 1  and the shortest distance is perpendicular to line x-y+3=0.

use point (-1,1)  and slope -1

use point and slope form

y-y1 =m(x-x1)
