Linear equations can be transformed by changing either the x -coefficient or the constant term.[br][br]Use this applet to see the effect of each change and relate this to a linear equation in the form [i]y[/i] =m[i]x[/i] + c[br][br]Turn the trace on to see copies of the line when you move the slider.

Note in these examples of Linear Equations [i]y[/i] is the subject of the equation. This is called the "slope intercept" form of a linear equation must be written with just [i]y[/i] on the left hand side.[br][br]The same is true for linear functions - f([i]x[/i]) =m[i]x[/i] + c - this is essentially the same as above but just uses a different notation.
