• If we know that there is a proportional relationship between y and x, then there will be a constant of proportionality between these variables, and what this is, is it is a number that I would have to multiply x by to get to y. So I could make a little table here, as we often do when we describe proportional relationships, x and y.

Notes: Let’s see what you remember from our vocabulary. Proportional Relationship If there is a proportional relationship between x and y, you can describe that relationship using the equation y = kx. The variable k is called the constant of proportionality, and it represents the constant rate of change or constant ratio between x and y. The value of k is represented by the equation k = _y x. Inversely Proportional: when one value decreases at the same rate that the other increases. Example: speed and travel time Speed and travel time are Inversely Proportional because the faster we go the shorter the time.
