You look for two good points on the graph, then you rise and run.( go up then move right or left)
To find the unit rate of any two numbers you divide:
9.60 divided by 4 = 2.4
Unit rate = $2.40
Hope I helped! :)
This function has a couple of restrictions:
- y can't be less than zero, because when you have no money left you can't buy any more tickets
- x must be a positive integer, because you can't buy a negative of fractional amount of tickets.
With these constraints in mind, we can explicitly write all the possible (x,y) couples:

Where x is the number of tickets bought and y is the amount of money you're left with. So, if you buy no tickets, you still have all your $60. If you buy 1 ticket you're left with $52. If you buy 2 tickets, you're left with $44, and so on.
This table shows that the domain is the set

And the range is the set

And they are both discrete. To graph the function, simply draw all the (x,y) couples on a coordinate grid.
As far as I can tell, is referring and assuming the ruler doesn't have any fractional values, namely it only has markings with integers.
so in short is asking, what are the two integers that the fractional 5¼ is between?
