First, the 3r + 2 s = 0 is just the equation for the line given above with r and s substituted for x and y, so disregard that part of the statements.
Statement 1 (3r +2 s)(4r +9 s) = 0 This is the same as 4r +9 s = 0 Since there are multiple values possible for r and s, it is impossible to tell.
Statement 2 (3r + 2 s) (4r6s) = 0 This is the same as 4r  6 s =0 Again, multiple possible values for r and s
Together: You have 2 distinct equations and 2 unknowns so you can solve for r and s, and determine if the solution set fits.
The answer is C.
