What is the slope of the line that passes through the points (-8,-1) and (-8,11)?

lubasha [3.4K]

Answer: $\text{Slope}=\Large\boxed{Unde fined}$

Step-by-step explanation:

Given information

$(x_1,~y_1)=(-8,~-1)$

$(x_2,~y_2)=(-8,~11)$

Given the formula for the slope

$\text{Slope}=\dfrac{\Delta y}{\Delta x}=\dfrac{y_2-y_1}{x_2-x_1}$

Substitute values into the formula

$\text{Slope}=\dfrac{(11)-(-1)}{(-8)-(-8)}$

Simplify the numerator and the denominator

$\text{Slope}=\dfrac{11+1}{-8+8}$

$\text{Slope}=\dfrac{12}{0}$

Simplify the fraction

$\text{Since any number divided by 0 is impossible to find, therefore: }$

$\text{Slope}=\Large\boxed{Unde fined}$

Hope this helps!! :)

What is the volume? __ cubic feet

Hunter-Best [27]

Answer:

128 ft³

Step-by-step explanation:

Volume of a prism is the area of the base times the height:

V = Ah

In the case of a triangular prism:

V = (1/2 bh) (L)

Given b = 8 ft, h = 4 ft, and L = 8 ft:

V = 1/2 (8 ft) (4 ft) (8 ft)

V = 128 ft³
