Question

Give the geometric representation of the following equation in one variable and in two variables. ½ [y-(2y-2)]= 5(y+1)​

Answer 1

(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'.
