The missing values are 2.5, 10 and 22.5
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Using equation (y2-y1)/(x2-x1) to find the slope.
Now using two points as (5, 12.5) and (6, 15.00)
So, (15-12.5)/(6-5)
=2.5/1
=2.5
Hence, single ticket costs 2.5
For 2 tickets,
= 2.5×2=5
The cost of two tickets is $5
For 4 tickets,
= 4×2.5=10
The cost of four tickets is $10
For 9 tickets,
= 2.5×9=22.5
The price of nine tickets is $22.5.
