EXERCISE 4.4
. Give the geometric representations of 3y+15=0 as an equation
(i) in one variable
(ii) in two variables​

Answer 1

$\orange{Answer}$

➔ Y = -5 is treated as an equation in one ➔variable, then it has a unique solution ➔y= -5. So it is a point on the number ➔line. ... x + y+5= 0, which is a linear ➔equation in two variables x and y.
