Question

Give geometrical representation of equation 3x+12=0 in

1)one variable 2)two variables

Answer 1

I have given the image of a similar kind of problem
(i)
In one variable, it is represented as:
x=−92

[In your question ,solution is x=-4.
so mark x=-4 instead of
X=-9/2=-4.5]

(ii) In two variables, it is represented as a line parallel to Y-axis.
3x+0y+12=0
x=-4
Y can take any value.
[According to your question,
The vertical line willwbe shifted from x=-4.5 to x=-4. In the below picture]
