Given:
A refreshment stand makes 2 large servings of frozen yogurt from 5 pints.
Let the number pints = x
And the number of the serving the frozen yogurt = y
so, we will have the equation:

when x = 5, y = 2
so,

so, the relation between (x) and (y) will be:

the graph of the line will be as shown in the following picture:
