Linear functions - Features

Linear functions are functions of the form f(x) = mx + c and their graphical representation is a straight line. m is the slope or the gradient of the line; it represents the steepness of the line. c is the y - intercept; where the line crosses the y - axis   If the straight line slopes upwards when moving from left to right, then the line has a positive slope or gradient. Equation of line: y = mx + c, where m > 0 Domain: R (the real numbers set) Range: R (the real numbers set)   If the straight line slopes downwards when moving from left to right, then the...
