Previous … WebbThere are many nonlinear direct proportion relationships such as y=kx^2 (a quadratic graph), y=kx^3 (a cubic graph), or y= \sqrt{x} (a radical graph). These are nonlinear functions as each graph is not a straight line, but x and y are still directly proportional to …
WebbThe "constant of proportionality" is the value that relates the two amounts Example: you are paid $20 an hour (continued) The constant of proportionality is 20 because: Earnings = 20 × Hours worked This can be written: y = kx Where k is the constant of proportionality Example: y is directly proportional to x, and when x=3 then y=15.
