HELP FAST I’LL MARK YOU BRAINLIEST What is the slope of a line perpendicular to the line whose equation is 6x+4y=72. Fully reduce your answer.

2/3

Step-by-step explanation:

6x + 4y = 72

-6x         -6x

4y = 72 - 6x

/4         /4

y = 18 - 6/4x

y = -6/4x + 18

perpidicular slope is the opposite reciprical of the original line:

-6/4 is the slope of the line above.

4/6  or 2/3 would be the desired slope

check:

the two slopes mutplied would equal -1

-6/4 x 2/3 = -12/12 = -1

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
