Answer -
Given:
The lines A, 2x + 3y =19 and B, 2x + 3y + 7 = 0 also a line C, 2x + 3y = 6.
Let d1 bethe distance between lines 2x + 3y = 19 and 2x + 3y = 6,
While d2 isthe distance between lines 2x + 3y + 7 = 0 and 2x + 3y = 6
Hence proved, thelines 2x + 3y = 19 and 2x + 3y + 7 = 0 are equidistant from the line 2x + 3y =6
