Question

Find the slope of the line that contains (-1,9) and (9,9).

Answer 1

Answer:

0

Step-by-step explanation:

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

Plug in the numbers.

$\frac{9-9}{9-(-1)}$

$\frac{0}{10}$

So, it would be 0.

0÷10=0

Answer 2

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
