Use the slope formula to find the slope of the line that passes through the given points .
sukhopar [10]

Answer: The result is a lemon with a velvety peel and an intense yet mellow lemony character—whose "texture is soft and flavor is deep," says Sortun. From there, the options are manifold. In On Food and Cooking, Harold McGee suggests that a solution of 5 to 10% salt is needed to achieve a good North African–style preserved lemon.

Salsk061 [2.6K]
PART A:
 The generic equation of the line is:
 y-yo = m (x-xo)
 First we look for the slope of the line:
 m = (y2-y1) / (x2-x1)
 m = ((5000) - (6000)) / (4-3)
 m = -1000
 Then, we substitute any point in the generic equation:
 (xo, yo) = (4, 5000)
 Substituting:
 y-5000 = (- 1000) (x-4)
 Rewriting:
 y = -1000x + 4000 + 5000
 y = -1000x + 9000
 The equation is:
 y = -1000x + 9000

 PART B: 
 For the price of 3.50 we have:
 y = -1000 * (3.5) +9000
 y = 5500

Round of 38828 to the nearest 10​
RUDIKE [14]

Step-by-step explanation:

We're going to be evaluating if we can round 2. (Values in the 10's place)


The value in the 'ones' place has to be greater than or equal to 5
in order to round up 2.

Since 8 is greater than 5, we can round up 2.

<u>Rounded answer:</u>
