Answer:

0

Step-by-step explanation:

When we have 2 points, we can find the slope from

m = (y2-y1)/(x2-x1)

   = (9-9)/(9--1)

   = 0/(9+1)

    = 0/10

Answer:

0

Step-by-step explanation:

Okay, so the formula is [tex]\frac{Rise}{Run}[/tex] but since you do not have a graph you can use the formula: [tex]\frac{Y_{2}-Y_{1} }{X_{2}-X_{1} }[/tex].

Plug in the numbers.

[tex]\frac{9-9}{9-(-1)}[/tex]

[tex]\frac{0}{10}[/tex]

So, it would be 0.

0÷10=0
