Answer:

Answer:

Intersecting lines

Solution: For intersecting line, the linear equations should meet following condition:

a  

2

 

a  

1

 

 

=  

b  

2

 

b  

1

 

 

For getting another equation to meet this criterion, multiply the coefficient of x with any number and multiply the coefficient of y with any other number. A possible equation can be as follows:

4x+9y−8=0

(b) Parallel lines

Solution: For parallel lines, the linear equations should meet following condition:

a  

2

 

a  

1

 

=  

b  

2

 

b  

1

 

 

=  

c  

2

 

c  

1

 

 

For getting another equation to meet this criterion, multiply the coefficients of x and y with the same number and multiply the constant term with any other number. A possible equation can be as follows:

4x+6y–24=0

(c) Coincident lines

Solution: For getting coincident lines, the equations should meet following condition;

a  

2

 

a  

1

 

=  

b  

2

 

b  

1

 

=  

c  

2

 

c  

1

 

 

For getting another equation to meet this criterion, multiply the whole equation with any n
