  • direct variation. Since (0, 0) is a solution of y = mx, the graph of a direct variation always passes through the origin and represents a proportional linear relationship. In the equation y = mx, m is called the constant of variation or constant of proportionality. It is the slope of the graph of y = mx. Vocab Words A direct variation is a relationship in which the ratio of y to x is a constant, m.

  • Graphs can also be used to represent direct variation, in which case the graph must be a straight line and pass through the origin. If the graph is a straight line, but does not pass through the origin, then the relationship it represents cannot be a direct variation. Direct variation should not be confused with linearity.

    Given any function of the form or , you know how to find the amplitude and period and how to use this information to graph the functions. Given a graph of a sine or cosine function, you also can determine the amplitude and period of the function. From this information, you can find values of a and b, and then a function that matches the graph. A line that passes through the origin has a y-intersect of zero, b = 0, and represents a direct variation. $$y=mx$$ In a direct variation the nonzero number m is called the constant of variation. You can name a function, f by using the function notion $$f\left ( x \right )=mx+b$$ f(x) is another name for y and is read as "the value of f at x" or "f of x". You can use other letters than f to name functions. Graphing Rational Functions, including Asymptotes. Graphing and Finding Roots of Polynomial Functions.
