Question

the general from of linear equation in two variables is (a)ax+by+c=d
(b) ax+b=0
(c)ax+by+c=0
(d)by+c=0
​

Answer 1

Answer:

If you not understand any problems,you can asked me.

(a)ax+by+c=d

or, ax+by=d-c

or, ax=d-c-by

or, a=d-c-by/x

(b)ax+b=0

or, ax=-b

or, a=-b/x

(c)ax+by+c=0

or, ax=-c-by

or, a=-c-by/x

(d)by+c=0

or, by=-c

or, b=-c/y
