A function that forms a linewhen graphed?

A function that forms a line when graphed is known as a linear function. It can be expressed in the form ( y = mx + b ), where ( m ) represents the slope of the line and ( b ) is the y-intercept. The graph of a linear function produces a straight line, and the slope indicates the direction and steepness of the line. Linear functions demonstrate a constant rate of change between the variables.
