    Two equations are given ax + by = c ix + ky = j (Replacing a, b, c, i, k, j by some numbers) 1. The lines are parallel 2.They intersect at 90 deg 3.They intersect. Which of the following are true A. 1and 2 B. 2 and 3 C. 1, 2 and 3 & so on…….. My Ans If 1 is true then 2&3 cannot be possible If 2 is true then 1 is not possible and 3 is true If 3 is true then option 1 is not possible but option may or may not be true => If 2 is true then 3 is obviously true
