If x = a, y = b is the solution of the equations x + y = 5 and 2x – 3y = 4, then the values of a and b are respectively

• 6, -1

• 2, 3

• 1,4

• 19/5, 6/5

The graph of x = -2 is a line parallel to the

• x-axis

• y-axis

• both x-axis and y-axis

• none of these

If in the equation x + 2y = 10, the value of y is 6, then the value of x will be

• -2

• 2

• 3

• -3

The pair of equations x = a and y = b graphically represents lines which are

• parallel

• intersecting at (b,a)

• coincident

• intersecting at (a,b)
