Question

Any equation which can be put in the form $ax+by+c=0$ where are $a,b,c$ are $\underline{\left(P\right)}$ and $a$ and $b$ are not both $\underline{\left(Q\right)}$ ,is called linear equation in $\underline{\left(R\right)}$ .

• A. $\left(P\right)$-constants, $\left(Q\right)$-zero ,$\left(R\right)$-three variables
• B. $\left(P\right)$-constants, $\left(Q\right)$-real number ,$\left(R\right)$-three variables
• C. $\left(P\right)$-real number, $\left(Q\right)$-zero ,$\left(R\right)$-two variables
• D. $\left(P\right)$-variables, $\left(Q\right)$-constants ,$\left(R\right)$-two variables

Answer 1

The correct option is C

$\left(P\right)$-real number, $\left(Q\right)$-zero ,$\left(R\right)$-two variables

Explanation for the correct option:

We know by definition that : An equation of a form $ax+by+c=0$, where $a,b,c$ are real numbers such that $a\ne 0\text{and}b\ne 0$ has two variables $x,y$.

Therefore we can conclude that : $\left(P\right)$-real number, $\left(Q\right)$-zero ,$\left(R\right)$-two variables

Hence, the correct option is C
