Q. 4

# <span lang="EN-US

Given:

Intercepts cut off on the coordinate axes by the line ax + by +8 = 0 ……(i)

And are equal in length but opposite in sign to those cut off by the line

2x – 3y +6 = 0 ……(ii)

Explanation:

The slope of two lines are equal

The slope of the line (i) is The slope of the line (ii) is  a The length of the perpendicular from the origin to the line (i) is

The formula used: d d1= d1= The length of the perpendicular from the origin to the line (ii) is

The formula used: d d2= Given: d1= d2 b = 4 Hence the value of a and b is Rate this question :
