Answer :

For any two lines to be at right angles, the angle between them should be θ = 90°.

a1a2 + b1b2 + c1c2 = 0, where a1, b1, c1 and a2, b2, c2 are the direction ratios of two lines.


The standard form of a pair of Cartesian lines is:


and …(i)


Now, first we rewrite the given equations according to the standard form, i.e.


and , i.e.


and …(ii)


Now, comparing (i) and (ii), we get


and


Now, as both the lines are at right angles,


so a1a2 + b1b2 + c1c2 = 0






11p = 70
