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>

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.

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

<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.

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

Hope this helps! :)

Please help i’ll mark u brainliest

Likurg_2 [28]

Answer:

there is a lot of solutions here is some guidance. so if there are more then 4 and less then 10 then every solution should equal 5, 6, 7,8, and 9. also it says the number of pencils is more then the number of pens so for example if it was to equal 9 i would put 5 + 4 . 5 is the number of pencils, 4 is the number of pens or i could put 6 + 3 so any numbers that equal to what i said; 5, 6, 7,8, and 9. good luck!

The length of a rectangle is 2 meters less than 2 times the width. The perimeter is 20 meters. Find the width.

kakasveta [241]

The equation you'd make would be (2x-2)+(2x-2)+x+x=20 because the length is 2 m less than the width (x). To simplify, it'd be 6x-4=20 because you combine like terms. You then move the -4 over to the 20 to make it 6x=24. The final answer is 4 meters.

Answer:

Step-by-step explanation:

hello,

for t = 4 hours

$d(4)=24^3+54^2-3=2*64+5*80-3=128+80-3=205$
