Line cd passes through points c (1,3) and d (4,-3). if the equation of the line is written in slope intercept form, y=my+b, what is the value of b?

b=5

Step-by-step explanation:

C(1,3) and point D(4,-3)

Since we want the equation in slope intercept form we must first calculate the slope (m):

By point slope formula and using point C (1,3) we have:

So the slope is -2 and the y -intercept (b) is 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.
