Answer:
Step-by-step explanation:
(i) In one variable
Given equation is 2x+9=0
⇒2x = −9
⇒x = -9 / 2
= − 4.5
(ii) Given equation is 2x + 9 = 0
⇒2x + 0y + 9 = 0
⇒2x = − 9
⇒x = - 9 / 2
= − 4.5
It is line parallel to y-axis at a negative distance.
Two points lying it are the points A(−4.5,0),B(−4.5,2).
