As we have a line, the function will be given by the expression:
F(X) = AX + B
where
<em>A = ΔY/ΔX</em>
<em>B = where the line intersects the Y axis</em>
Looking at the graph we have already concluded that
B = - 3
A = ΔY/ΔX
A = (5 - 3)/(4 - 3) see attached picture
A = 2
So,
F(X) = AX + B
<h2>F(X) = 2X - 3</h2>
Simplified expression that represents the cost of renting 6 scooters is 18 j +30
<u>Step-by-step explanation:</u>
Given data:
The cost of renting of a scooter is represented by 3j +5
So, from that, we can say in general,
The cost of renting of n scooters is represented by

But according to given, the value of n is 6. i.e. to find the cost for six number of scooters. We can calculate now as follows
So, the cost of renting of a scooter is represented by
