Answer:

The value is  m  = 0.9022

Step-by-step explanation:

From the question we are told that

    The length of the treads is  a =  9 \  inch

     The length of the risers is  b  =  8.12 \  inch

Generally the slope of the staircase is

         m  =  \frac{b}{a}

=>       m  =  \frac{8.12}{9}

=>       m  = 0.9022

Answer:

The slope of this line is -2/3x.

Step-by-step explanation:

The slope can be found by getting x1 and y1 (0,3) and x2 and y2 (3,1). Once you have these you would do y2 - y1 / x2 - x1.

And the equation then is

1 - 3 / 3 - 0.  After simplifying this you get -2/3.
