Answer:

y = - 3x + 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line

m = $\frac{-2-4}{2-0}$ = $\frac{-6}{2}$ = - 3

Note the line crosses the y- axis at (0, 4) ⇒ c = 4

y = - 3x + 4 ← equation of line

Which of the following is an equation in slope-intercept form of the line that passes through the given point and with the given

Diano4ka-milaya [45]

Answer:

$y=2x-14$

Step-by-step explanation:

we know that

The equation of the line in slope intercept form is equal to

$y=mx+b$

where

m is the slope

b is the y-intercept

In this problem we have

$m=2\\point\ (9,4)$

substitute the given in the equation

$4=2(9)+b$

Solve for b

$4=18+b$

subtract 18 both sides

$4-18=b$

$b=-14$

therefore

The linear equation in slope intercept form is equal to

$y=2x-14$

Money must serve as ___

Molodets [167]

Money must serve as a medium of exchange, a storehouse of value and a unit of account

Answer: Option B, D, and E

<u>Step-by-step explanation:</u>

Money, the term coined in terms of the following three services.

Medium of exchange played as important role to facilitate transactions. Think scenario like without money, then all operations would be exchanged as one product or service exchange for another (barter system).
To be in above, money must retain its value over time i.e store of value. Failure to save money for some time and still remain valuable in return would not resolve the double overlap of desires and therefore would not be accepted as a medium of exchange.
Money also acts as a units of account and is a regular measure of the cost of goods and service exchanged. Knowing the value of a good or the price in cash, both the supplier and buyer can decide how much to deliver and how much to buy.

11x + 2y = 68 & 5x + y = 13

matrenka [14]

Answer:

i hope its correct

Step-by-step explanation:

11x + 2y=68 ------------1

5x+y=13 ------------2

y= 13-5x. ------------3

put 3 into 1

11x +2(13-5x) =68

11x +26 -10x =68

x=42

put x =42 into 2

5(42) +y =13

210+y=13

y=13-210

y=197
