Please help me solve this equation :Given the points (1,-5) and (4,3) find the slope.
~~~~~~~~~~~~~~~~~~~~

The formula for the slope of a straight line passing through two given points    (x%5B1%5D,y%5B1%5D)    and    (x%5B2%5D,y%5B2%5D)    is

    m = %28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29.


In your case, x%5B1%5D = 1,  y%5B1%5D = -5,  x%5B2%5D = 4,  y%5B2%5D = 3,


Substitute these values into the formula and calculate

    m = %283-%28-5%29%29%2F%284-1%29 = 8%2F3.


Answer.  The slope is 8%2F3.

Solved.
