Transformation of Linear Functions
Linear equations can be transformed by changing either the x -coefficient or the constant term. Use this applet to see the effect of each change and relate this to a linear equation in the form y =mx + c Turn the trace on to see copies of the line when you move the slider.
Note in these examples of Linear Equations y is the subject of the equation. This is called the "slope intercept" form of a linear equation must be written with just y on the left hand side. The same is true for linear functions - f(x) =mx + c - this is essentially the same as above but just uses a different notation.
