Give the geometrical representation of 2x + 13 = 0 as an equation in
(i) one variable (ii) two variables
We are given,
2x + 13 = 0
2x = -13
x = -13/2
The representation of the solution on the number line, when given equation is treated as an equation in one variable.
The representation of the solution on the Cartesian plane, it is a line parallel to y axis passing through the point (-13/2, 0) is shown below.
