(-5,-8) and (-2,1) find the slope of the line containing the pair points

To solve we have to use the formula:

m= Y2-Y1/X2-X1

X1= -5

Y1= -8

X2= -2

Y2= 1

Use the values into the formula for the slope.

b= -8 =(3) x (-5) = 7

Then the equation of the line can be written in the form of y=mx+b

y=3x+7

The slope is m=3

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.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
