Answer:

<h2>-4</h2>

Option B is the correct option

Step-by-step explanation:

Let the points be A and B

A ( -1 , 8 ) -----> ( x1 , y1 )

B ( 2 , -4 ) -----> ( x2 , y2 )

Now, let's find the slope of the line:

\frac{y2 - y1}{x2 - x1}

plug the values

=  \frac{ - 4 - 8}{2 - ( - 1)}

Calculate the difference

\frac{ - 12}{2 - ( - 1)}

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression

\frac{ - 12}{2 + 1}

Add the numbers

=  \frac{ - 12}{3}

Reduce the fraction with 3

=  - 4

Hope this helps..

Best regards!!

MULTIPLE CHOICE 9th grade math: help me find the formula to the nth term:
maxonik [38]

Answer:

a_{n} = - 5n - 2

Step-by-step explanation:

There is a common difference between consecutive terms, that is

- 12 - (- 7) = - 17 - (- 12) = - 5

This indicates the sequence is arithmetic with n th term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 5, then

a_{n} = - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
