Constant of Proportionality Pg. 40 & 41 RS

The constant of proportionality is a constant ratio (unit rate) in any proportional relationship.

The constant of proportionality is a constant ratio (unit rate) in any proportional relationship. We use the letter k to represent the constant of proportionality. Equations: y = kx or k = y x

We can find the constant of proportionality from a table of values, equation and

We can find the constant of proportionality from a table of values, equation and a graph. In a table, simplify any one of the ratios (since we already know that the table is proportional). Chaperones 1 2 3 4 5 Students 12 24 36 48 60

In a graph, choose a point (x, y) to find and simplify the ratio
