Question

the graph of the equation ax+b=0(a and b are constants and a#0, b#0) is a) parallel to x-axis b) parallel to Y-axis c) passing through origin d) not passing through origin (MCQ)​

Answer 1

1. parallel to x-axis

my answer write

Answer 2

Given,

The equation given is $\[ax + b = 0\]$ where$\[a \ne 0\]$ and $\[b \ne 0\]$ respectively.

Solution,

Calculate the value of $\[x\]$ for the given equation.

So,

$\[\begin{array}{l} \Rightarrow ax + b = 0\\ \Rightarrow ax = - b\\ \Rightarrow x = - \frac{b}{a}\end{array}\]$

Therefore, it is clear that the line is parallel to the y-axis.

Hence, the correct option is (b) i.e. parallel to Y-axis.
