The Total solution for NCERT class 6-12
The normal forms ofthe lines 3x − 4y + 4 = 0 and 2x + 4y − 5 = 0.
Let us find, in givennormal form of a line, which is nearer to the origin.
-3x + 4y = 4
Now 2x + 4y = – 5
-2x – 4y = 5
From equations (1) and(2):
45 < 525
∴ The line 3x − 4y+ 4 = 0 is nearer to the origin.
