Hi Tiara, hope this solution helps:
line l:
y = -3x + 9
y intercept = 9
line m:
3y = -2x + 12
x intercept = 6
-9x + 27 = -2x + 12
7x = 15
x = 15\7
y = 9 - 45/7 = 18/7
ratio area of triangles R1 : R2
= 1/2*(9-18/7)*15/7 : 1/2*(6-15/7)*18/7
= 45/7*15/7 : 27/7*18/7
=45*15 : 27*18
=5*15 : 3*18
=5*5 : 18
=25 : 8
