Question 4 Any solution ofthe linear equation 2x+0y+9=0 in two variables is of the form:
A) (−92,m)
B) (n,−92)
C) (0,−92)
D) (−9,0)
Open in App
Solution
The answer is A.
The given linear equation is,
2x + 0y + 9 = 0 ⇒ 2x + 9 = 0 ⇒ 2x = -9 ∴x=−92and y can be any real number
Hence (−92,m)is the required form of the solution of given linear equation where m can be any real number.
