Answer:

<u>y = 1</u>

Step-by-step explanation:

<u>Given</u>

y ∝ x⁴

⇒ y = kx⁴

<u>Finding the proportionality constant, k</u>

y = 16 and x = 3
16 = k (6)⁴
16 = 1296k
k = 16/1296
k = 1/81

<u>Finding y</u>

y = 1/81 x (3)⁴
y = 1/81 x (81)
<u>y = 1</u>

What is the slope of the line that passes through the points (-4, 4) and (-6, 6)

Svet_ta [14]

Answer:

-1

Step-by-step explanation:

$\boxed{slope = \frac{y1 - y2}{x1 - x2} }$

(x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

Slope of the line

$= \frac{4 - 6}{ - 4 - ( - 6)}$

$= \frac{ - 2}{ - 4 + 6}$

$= \frac{ - 2}{2}$

= -1
