Rewrite each equation in slope intersept form to 4x -y=7

y = 4x-7

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

4x-y = 7

Subtract 4x from each side

-y = -4x+7

Multiply each side by -1

y = 4x-7

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.

exactly you go it
