A line has a slope of - 4 and includes the points (6,v) and (3,3). What is the value of v?
labwork [276]

Answer:  v = - 9


Step-by-step explanation:

Since two points on the line are given, we use formula for slope.

Let (a,b) and (c,d) be two points on the line, the slope of the line is given by

m=\frac{d-b}{c-a}.

Hence, using this we have

-4=\frac{3-v}{3-6}

Thus, we have

-4×(-3)=3-v⇒12=3-v⇒12-3=-v⇒v=-9

Indicate a general rule for the nth term of this sequence. -6b, -3b, 0b, 3b, 6b. . .
GREYUIT [131]

Answer:

a(n) = -16b + (n - 1)(3b)

Step-by-step explanation:

First term is -6b.

Common difference is 3b; each new term is equal to the previous one, plus 3b.

Formula for this arithmetic sequence is

a(n) = -16b + (n - 1)(3b)
