The relationship between the number of hours worked \(x\) and earnings \(y\) (in ₹) is linear, given by:
 
\(y=25x+20\)
 
a) Identify the fixed amount and the rate per hour.
 
Rate per hour \(=\)  
 
Fixed amount \(=\)

b) Draw the graph using values from \(x=0\) to \(x=3\).
 
\(x\) \(0\) \(1\) \(2\) \(3\)
\(y\)
