Question

Sketch the graph of the equation 3x=-12

Answer 1

The given expression is,

`3x=-12`

Divide both sides of the above equation by 3. (Dividinng the equation by a constant does not affect the equation).

`\begin{gathered} x=(-12)/(3) \\ x=-4 \end{gathered}`

Now, we plot x=-4 in the graph.

So, the graph of equation 3x=-12 is a vertical line passing through x=-4.
