What is the slope? Please answer with a pic and some work

m = rise over run

Rise: y/2 - y/1

Run: x/2 - x/1

m=slope

(x_1, y_1)=coordinates of first point in the line

(x_2, y_2)=coordinates of second point in the line

Step-by-step explanation:

slope= (y2-y1)/(x2-x1)

1) (2-1)/(3-2)

=m=1

3) (5-4)/(2-2)

= UNDEFINED (vertical line)

5) (-6-6)/(3-(-3)

(-12/6)

= -2

CHECK

y=mx+b

6=-2(-3)+b

6=6+b

b=0

y=-2x connects both of these points on a graph

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.
