Question

describe the graph of of the equation x = -2. Is the equation a function?

Answer 1

In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot. 

If x-intercept is -2 the line would be vertical as the y-intercept = 0. 

Answer 2

Answer:

A. vertical line: yes.

Step-by-step explanation:

When we have an equation with only one variable, that means it represents a vertical or horizontal line.

When the equation has the form $x=k$, where $k$ is a real number, then it represents a vertical line, because its value is horizontally fixed.

Now, in this case we have the equation

$x=-2$

As we said before, this equation represents a vertical line which passes through $x=-2$.

Therefore, the right answer is A. vertical line: yes.
