The line passes through (3, a), (2, 4) and (b, 4). The line passes through (2, 4) and (b, 4). This is the case when the line is horizontal and the equation of the line is y = 4
As it passes through (3, a), a = 4
y = 4 is true for any value of b where b is the x-coordinate of a point (b, 4)
The required value of a = 4 and b can take on any value.
