Answer:

B. y = 2x - 9

Step-by-step explanation:

All of the answer choices has a slope of 2, but B is the only answer choice that has (4,-1) on its line.

You can tell by plugging the point into the equation and seeing if the result is true.

y = 2x - 9

-1 = 2(4) - 9

-1 = 8 - 9

-1 = -1

What is the perpendicular slope to 6/-3

IRISSAK [1]

Answer:

Perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

Given:

Let the perpendicular slope be x.

The given slope is $\frac{6}{-3}$

For perpendicular slopes, the product of the slopes is equal to -1.

Therefore, $x\times \frac{6}{-3}=-1\\-\frac{6}{3}x=-1\\6x=3\\x=\frac{3}{6}=\frac{1}{2}$

Therefore, the perpendicular slope is $\frac{3}{6}$ or $\frac{1}{2}$ .

Step-by-step explanation:

8). CA = 9.20 ( multiply the given decimal by 100)

AB = 10.80

CB = 8.50

9). option e is correct side - side - side

10). SSS

11). 1 ( because with the given info. u can calculate the perimeter of the traingle only )

12) through the given info we can only find the perimeter of the traingle

so,

perimeter = sum of all sides

→ 9.2 + 8.5 + 10.8 = 28.5 m

hope this answer helps you dear...take care may u have a great day ahead!
