Question

In the general equation of a line, if A = 0, what will the graph of the line look like? It will be vertical. It will be horizontal. It will be equivalent to the graph of y = x. There is not enough information to tell.

Answer 1

it would look like By = C. or y =C/B which is horizontal

Answer 2

Answer:

Option B.

Step-by-step explanation:

The general equation of line is

$Ax+By+C=0$

where, A,B and C are real numbers.

If A=0, then

$A(0)+By+C=0$

$By+C=0$

$By=-C$

Divide both sides by B.

$y=-\dfrac{C}{B}$

Here, -C/B is a real number.

We know that y=a is a horizontal line, with y-intercept at (0,a).

So, $y=-\dfrac{C}{B}$ is a horizontal line, with y-intercept at (0,-C/B).

Therefore, the correct option is B.
