What is the y intercept of the line described for the equation below? y=4x-9

Assuming that it's already in the standard form - y=mx+b | Your Y-Intercept is going to be -9

Step-by-step explanation:

Using the equation y=mx+b, anything that is in place of the (b) is your Y-Intercept and your slope is (m)

The y intercept is (0, -9)

Step-by-step explanation:

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.
