What is the equation of the graphed line written in standard form? a. –3x + y = –4 b. y = 3x – 4 c. y + 3x = 4 d. 3x – y = 4

D. 3x – y = 4

Step-by-step explanation: Standard form of a linear equation is of the form

ax+by =c.

We are given two points on the graph (2,2) and (0,-4).

Slope of the line: m =.

Applying point-slope form

y-y1 = m(x-x1)

y-2 = 3(x-2)

y-2 = 3x -6

Adding 2 on both sides, we get

y-2+2 = 3x -6+2

y = 3x - 4

Subtracting 3x from both sides, we get

y -3x = 3x-3x - 4

-3x + y= -4.

Multiplying whole equation by -1, we get

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

the answer is c just got it on ed
