M y 2 - y 1 x 2 - x 1 Substitute 4 -2 for x 1 y 1 and -1 2 for x 2 y 2. To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. In case of a curve to find the slope we have to differentiate the equation of the curve and then for different value of x we can calculate slope at that point.
GoldD y_2 - y_1 y2.
The formula to calculate slope is given as Slope of a Line m y 2 - y 1 x 2 - x 1 Where m is the slope of the line. If the equation is not in this form try to rearrange the equation.
