2x+y= -5 is our equation and it passes through (4, -3)

point-slope formula= y-y1= m(x-x1)

fill in your formula, but flip the slope so its perpendicular. so slope is 1/2.

y+3=1/2(x-4) when i filled the formula in, i used 4 as x1 and -3 as y1.

y+3=1/2x-2 multiply x and -4 by 1/2

y=1/2x-5 subtract 3 from both sides.

Final answer: y=1/2x-5

Also, i'm sorry my answer took so long the bell rang and so I had to leave this alone for a minute. Feel free to ask any questions :)

The correct answer is: [D]: " 576π cm³ " .

____________________________________________________


Explanation:

____________________________________________________


Use the formula for the volume, "V", of a cylinder, to find the volume of the given cylinder:

____________________________________________________


V = π r² h ;

in which:


V = volume (for which we shall solve).

π = π ; All the answer choices given are in terms of 'π' ;


r = radius = 6 cm (given);


h = height = 16 cm (given);

__________________________________________________________

Plug in these values into the formula to solve for the volume, "V" :


V = π r² h


= π * (6 cm)² * (16 cm) ;


= π * (6²) * (cm²) * (16 cm) ;


= π * (6*6) * 16 * cm³ ;


= π * (36) * 16 * cm³ ;


= π * (36 * 16) * cm³

___________________________________________________________

V = 576 π cm³ ; which is: Answer choice: [D]: " 576π cm³ " .
