In a normal proportionality relationship , the constant of proportionality is the multiplicand that links one of the variable to the other one. The graph will always have a positive slope because the two quantities increase or decrease together. 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. In this example, it is already known that the relation is indirect, so the equation used will be y = k/x, or xy = k. Simply plug in x = 5 and y = 1, and the equation for this relation is {eq}5\ \times\ 1\ =\ k {/eq}. -Key When she drives at a speed of 40 miles per hour (x = 40), it takes her 2 hours to get home (y = 2).
