Question

Give the geometric representation 2y=5 as an equation in one variable and in two variable

Answer 1

Answer:

2y-5=0 (equation in 1 variable)

0x^2+2y-5=0 (equation in 2 variable)

Answer 2

(a) In one variable

• The linear equations in one variable is an equation which is expressed in the form of ax+b = 0, where a and b are two integers, and x is a variable and has only one solution.

2y-5=0

⇒2y=5 ………….(i)

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

(b) In two variables

• An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.

2y-5=0

⇒2y=5

⇒0x+2y=5 ……….(ii)

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