I need the answer for this quetion:

Give the geometric representation of 2x+9=0 as an  equation :  a) in one variable  b) in two variable .

a) The given equation is a one variable equation of the form a x +b = 0

so its representation as 

2x + 9 = 0 or 2x = - 9 both are correct.

b) To represent it in two variable equation of the form ax + by + c = 0

write it as

2x + 0y + 9=0
