Answer:

it's B, C, and D

Step-by-step explanation:

A. w ⋅ 462 = 16 1/2

not A

w * a ≠ l

B. 16 1/2 ⋅ w = 462

is B

l * w = a

C. 462 ÷ 16 1/2 = w

is C

a / l = w

D. 462 ÷ w = 16 1/2

is D

a / w = l

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope

IrinaVladis [17]

Answer:

The correct answer is option B.

Step-by-step explanation:

Two point form of the equation:

$(y-y_1)=\frac{y_2-y_1}{x_2-x_1}\times (x-x_1)$

$\frac{y_2-y_1}{x_2-x_1}=Slope=m$

$(y-y_1)=m\times (x-x_1)$

A line passing through the point (-1,6) with slope ,m = -3.

The equation of the line will be:

$y-6=(-3)(x-(-1))=(-3)(x+1)$

Hence, the correct answer is option B.
