Slope Of A Line

The formula for the slope of the line joining two points and is: For the points and , the slope is given as 2. Therefore, we can use the formula: Simplifying the left-hand side: Now, multiply both sides by : Expanding the right-hand side: Solving for :

The correct option is (A):

The slope of the line joining two points and is given by $ (x_1, y_1) = (4, 2) (x_2, y_2) = (3, -k) $
