JEE Main 6 April 2023, Shift 1, Maths Q12

Question 12 of 90 in this shift, Maths question 12 of 30, Section A.

The straight lines

l_1

and

l_2

pass through the origin and trisect the line segment of the line

L: 9x+5y=45

between the axes. If

m_1

and

m_2

are the slopes of the lines

l_1

and

l_2

, then the point of intersection of the line

y=(m_1+m_2)x

with

L

lies on

(1) $y-2x=5$
(2) $6x-y=15$
(3) $y-x=5$ Official answer
(4) $6x+y=10$
