This pair of linear equations is

• Consistent

• Inconsistent

• Consistent

• Inconsistent

• Dependent

• None of the above

The pair of linear equations:
 kx + 4y = 5 ; 3x + 2y = 5
 is consistent only when:

• k ≠ 6

• k = 6

• k ≠ 3

• x = 3

If the system of equations kx - 5y = 2, 6x + 2y = 7 has no solution, then k =___

• -10

• -5

• -6

• -15

If a pair of linear equations is consistent, then the lines will be 

•  parallel

• always coincident

• intersecting or coincident

•  always intersecting

Find whether the following pair of linear equations is consistent or inconsistent : 3x+2y = 8 6x - 4y = 9 ( 1 mark )
