Read and Discuss. The graph of a proportional relationship between two quantities is a straight line that starts at the origin, (0, 0). These graphs show the proportional relationship between tricycles and wheels. In the graph of w = 3 t, the x -axis represents the number of tricycles ( t ). The y -axis represents the number of wheels ( w ).Aug 15, 2020 · When two quantities x and y are in a proportional relationship, we can write the equation y = kx and say, “ y is proportional to x .”. In this case, the number k is the corresponding constant of proportionality. We can also write the equation x = 1 ky and say, “ x is proportional to y .”.

The equation is y = 5x y = 5 x . Now substitute x = 100 x = 100 and find y y . y = 5 ⋅ 100 y = 500 y = 5 ⋅ 100 y = 500. Direct variation describes a simple relationship ...Speed and travel time are Inversely Proportional because the faster we go the shorter the time. As speed goes up, travel time goes down. And as speed goes down, travel time goes up. This: y is inversely proportional to x. Is the same thing as: y is directly proportional to 1/x. Which can be written: y = k x.
