The first thing you should know is the gradient definition for a line. The gradient of a straight line tells us how much inclination it has. Therefore, the gradient of a line represents the slope of the line. We have then that the generic equation of the line is: y-yo = m (x-xo) Substituting the values: y-3 = 3 (x-2) Rewriting: y-3 = 3x-6 y = 3x-6 + 3 y = 3x-3 y = 3 (x-1) Answer: The equation of the line is: y = 3 (x-1)
