Question 88

Which of the following points lies on the line 3x - 4y = -13?

Solution

The point that satisfies the equation $$3x - 4y = -13$$ lies on it

(A) : (-5,-7) : $$(3 \times -5) - (4 \times -7)$$ = 13

(B) : (5,7) : $$(3 \times 5) - (4 \times 7)$$ = -13 = R.H.S.

(C) : (-5,7) : $$(3 \times -5) - (4 \times 7)$$ = -43

(D) : (5,-7) : $$(3 \times 5) - (4 \times -7)$$ = 43

=> Ans - (B)
