Slope = (1 + 4)/(5 - 3) = 5/2

y = mx + b
1 = 5/2(5) + b
1 = 25/2 + b
b = 1 - 25/2
b = -23/2

equation
y = 5/2x - 23/2

standard form
5/2x - y = 23/2
or
5x - 2y = 23

hope it helps

Solve for y<br> 4.2x - 1.4y = 2.1
Harlamova29_29 [7]
4.2x - 1.4y = 2.1    |multiply both sides by 10

42x - 14y = 21    |subtract 42x from both sides

-14y = 21 - 42x    |change signs

14y = 42x - 21    |divide both sides by 14

y = 3x - 1.5

Three co-workers are packing books in a storage bin. The bin is 4 feet high, 9 feet long, and 11 feet wide. If 6 books fill 1 cu
evablogger [386]

Alright, lets get started.

Height of the bin = 4 ft

Length of the bin = 9 ft

Width of the bin = 11 ft

Volume of the bin = L*W*H

Volume V = 9*11*4

Volume V= 396 cubic feet

6 books fiils 1 cubic feet

or

1 cubic feet is filled by = 6 books

So, 396 cubic feet is filles by = 396 * 6

So, 396 cubic feet is filles by =2376 books

It means 2376 books will fit in the storage bin. : Answer

Hope it will help :)

Please Help I will mark brainliest !!!
arsen [322]

Answer:

No

Step-by-step explanation:

If the lines are perpendicular then they will be the negative reciprocals of each other.

Calculate the slope using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = P(- 8, - 10) and (x₂, y₂ ) = Q(- 5, - 12)

m_{PQ} = \frac{-12+10}{-5+8} = - \frac{2}{3}

Repeat the process with

(x₁, y₁ ) = R(9, - 6) and (x₂, y₂ ) = S(17, - 5)

m_{RS} = \frac{-5+6}{17-9} = \frac{1}{8}

The slopes are not the negative reciprocal of each other, thus they are not perpendicular.
