Equations for proportional relationships

So when I went to the practice: writing proportional equations, it said "A unicorn daycare center requires there to be 2 supervisors for every 18 unicorns. Write an equation that shows the relationship between the number of supervisors (n) and the number of unicorns (u). I put n=9u because n= 1 supervisor and 9u= 9 unicorns.

Represent proportional relationships by equations. For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t=pn. Explain what a point (x,y) on the graph of a proportional relationship means in terms of the situation ...Proportion says that two ratios (or fractions) are equal. Example: We see that 1-out-of-3 is equal to 2-out-of-6. The ratios are the same, so they are in proportion. Example: Rope. A rope's length and weight are in proportion. When 20m of rope weighs 1kg , then: 40m of that rope weighs 2kg. 200m of that rope weighs 10kg.The equation of a proportional relationship is of the form \(y=kx\), where \(k\) is a positive number, and the graph is a line through \((0,0)\).
