Answer:

y=-2x+4

Step-by-step explanation:

we use the formula for the line and substitute what we already know, which is that the y-intercept is (0,4):

y=mx+4

then, you use the formula for slope:

Δy/Δx

(4-0)/(0-2)

4/-2

-2

you substitute the slope into the equation and the answer:

y=-2x+4

Hope this helps :)

P.S: m is the variable for the slope

What is the common ratio of the sequence?<br> -2,6,-18,54
aivan3 [116]

<u>ANSWER</u>

The common ratio is -3.

<u>EXPLANATION</u>

In general, the common ratio of a Geometric Sequence is given by:

r = \frac{a_{n+1}}{a_{n}}

We can find the common ratio using any two consecutive terms of the geometric sequence by dividing the subsequent term by the previous term.

The given sequence is -2,6,-18,54

Using the first two terms the common ratio is

r =  \frac{6}{ - 2}  =  - 3

We could also used the second and third terms to get

r =  \frac{ - 18}{6}  =  - 3

and so on and so forth.

Therefore the common ratio is -3.
