Answer:

D. negative

Step-by-step explanation:

Let's analyze each answer choice.

A. Zero

A line with a zero slope is a horizontal line. The x values change, but the y values stay the same.

B. Undefined

A line with an undefined slope is a vertical line. The x values don't change and the y values vary.

C. Positive

When a line has a positive slope, the line increases from left to right.

D. Negative

When a line has a negative slope, the line decreases from left to right.

When we move from left to right on the graph, the line moves down. Therefore, this line must have a negative slope and D is correct.

What is the slope of the line that passes through the points (-10, -8) and

bazaltina [42]

First of all we have to find the slope

m = y₂-y₁ / x₂-x₁

m = -8 + 16 / -10 + 8

m = 8/-2

m = -4

y-y₁ = m (x-x₁)

y + 8 = -4 (x + 10)

y + 8 = -4x - 40

y = -4x -40 - 8

y = -4x -48

The 6 term of a G.P is -2\27 and it's first term is 18.what is the common ratio

Airida [17]

Answer:

r = - $\frac{1}{3}$

Step-by-step explanation:

The n th term of a GP is

$a_{n}$ = a₁ $r^{n-1}$

where a₁ is the first term and r the common ratio

Here a₁ = 18 and a₆ = - $\frac{2}{27}$ , then

18 $r^{5}$ = - $\frac{2}{27}$ ( divide both sides by 18 )

$r^{5}$ = - $\frac{1}{243}$ ( take the fifth root of both sides )

r = $\sqrt[5]{-\frac{1}{243} }$ = - $\frac{1}{3}$
