(3,4)(2,-6) in slope intercept form

y=10x-26

Step-by-step explanation:

1.find the slope

m=y2-y1/x2-x1

m=-6-4/2-3

m=-10/-1

m=10

2.y-y1=m(x-x1)

  y-4=10(x-3)

  y-4=10x-30

  y=10x-30+4

  y=10x-26

11 feet 6 inches and 8 feet 6 inches

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
