Find the value of r so the line that passes through each pair of points has the given slope (7,,6),m=0 m=0

The slope m of a straight line passing through points (x₁,x₂) and (y₁,y₂) can be calculated like this:

                                           m = change in y-value /  change in x-value

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

We are given the points as (7,r) and (4,6) and slope m=0 . Substituting these:

⇒m = 6 - r / 4 - 7

⇒0 = 6 - r / -3

∴ r = 6

step-by-step explanation:

i hope this : )

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.
