The slope of a line is the steepness of the line. In this case we must use another special formula. So let me write this down.
So let me write this down.
So putting the values of Dy D y and Dx D x in the equation of slope we know that. The basic formula for a linear equation is y mx b where m is the slope. Often times a graph is not present and we must calculate the slope when given two ordered pairs. Y - y1 m x - x1 y1 x1 the coordinates of the point you know.
