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
