Question

give the geometrical representation of 2y+7=0 as in one variable and two varia​

Answer 1

Answer:

(a) In one variable,

2y+7=0

⇒2y=−7 ………….(i)

Equation (i) is an equation of one variable i.e., 'y'.

(b) In two variables,

2y+7=0

⇒2y=−7

⇒0x+2y=−7 ……….(ii)

Equation (ii) is represented as an equation of two variables i.e., 'x' and 'y'.
