M= 1/2 and point : (4,-3)

Please help I will give you brainless

y=1/2x-5

Step-by-step explanation:

We have slope so we just need to find the y intercept.

slope intercept formula is

y=mx+b

(m) is slope

(b) is y int

y=1/2x+b

now apply our given x and y values (4 & -3)

-3=1/2(4)+b

simplify

-3=2+b

subtract 2 from each side

-5=b

put that into our equation

y=1/2x-5

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.
