What is the equation of the line, in point-slope form, that passes through the points (-7, -10) and (-6, -8)?
Softa [21]

Hi!

<h3>The equation of point slope form is</h3>

<u>y = sx + b</u>

We need to find s and b

s = slope

b = y intercept

-------------------------------

<h3>To find the slope, use this formula. </h3>

\frac{y2-y1}{x2-x1}

Put in the values.

\frac{-8-(-10)}{-6-(-7)} = \frac{2}{1}simplify = 2

The slope is 2.

<u>y = 2x + b</u>

------------------------------------

<h3>Now we need to find the y intercept. Put in a point, and solve for b. </h3>

-8 = 2 * -6 + b

-8 = -12 + b

4 = b

The y intercept is 4.

<u>y = 2x + 4</u>

<h2>The answer y = 2x + 4</h2>

Hope this helps! :)

I don't understand please help ​
dybincka [34]

Answer:

Step-by-step explanation:

If she sells 8 dozen, she will get exactly 120 dollars. But that is not what the question says.

Sales = 8 * 15 = 120

The question says that she wants to make more than 120 dollars. Therefore the circle must be an open one. B is the proper answer. A is close but A means that she is willing to stop her sales when they reach 120 dollars. Not so.

A is not the answer.
