There are several information's already given in the question. Lat us first write them down and then go for solving the problem.
Total number of pupil <span>in Secondary one = 225
Let us assume the number of pupil who do not pay the school fees through GIRO scheme = x
Then
Number </span>of pupil who pay the school fees through GIRO scheme = 14x
So
x + 14x = 225
15x = 225
x = 15
From the above deduction, it can be concluded that 15 pupil did not join the scheme.

The y intercept of the graphed function and the equation are both -2
(I'm not entirely sure what the question is asking as some of it is blocked out from the drop down box?)
