Reduce each of the following equations to normal form :
(i) x + y - 2 = 0
(ii) 
(iii) x + 5 = 0
(iv) 2y – 3 =0
(v) 4x + 3y - 9 = 0
If the equation is in the form of ax + by = c, to get into the normal form we should divide it by 
, so now
Divide by 
= 
This is in the form of 
, where 
and 
Conclusion: 
+ 
= 
is the normal form of x + y - 2 = 0
(ii) 
⇒x + y = - √2
If the equation is in the form of ax + by = c, to get into the normal form, we should divide it by
, so now
Divide by 
Our new equation is 
This is in the form of 
, where 
and p =1
Conclusion: 
is the normal form of 
(iii) 
If the equation is in the form of ax + by = c, to get into the normal form, we should divide it by
, so now
Divide the equation by 
Our new equation is 
This is in the form of 
, where 
and p = 5
Conclusion: 
is the normal form of 
(iv) 
If the equation is in the form of ax + by = c, to get into the normal form, we should divide it by
, so now
Divide by 
Our new equation is 
This is in the form of

and 
Conclusion: 
is the normal form of 
(v) 
If the equation is in the form of ax + by = c, to get into the normal form, we should divide it by 
, so now
Divide by 
Our new equation is
