Final Answer : False, Explanation :   The slope of a line passing through two points   ( x 1 , y 1 ) (x_1, y_1) ( x 1 ​ , y 1 ​ )   and   ( x 2 , y 2 ) (x_2, y_2) ( x 2 ​ , y 2 ​ )   is given by   m = y 2 − y 1 x 2 − x 1 m = \frac{y_2 - y_1}{x_2 - x_1} m = x 2 ​ − x 1 ​ y 2 ​ − y 1 ​ ​  . Substituting the given points,   m = 10 − 5 10 − 20 = 5 − 10 = − 1 2 m = \frac{10 - 5}{10 - 20} = \frac{5}{-10} = -\frac{1}{2} m = 10 − 20 10 − 5 ​ = − 10 5 ​ = − 2 1 ​  .

If a line passes through the points (20,5) and (10,10), then the slope of the line is 1/2.
