Write the equation of the line given points (-4,6) and (-8,10)

Advocard [28]

Answer:

the equation of the line in slope-intercept form is: $y=-x+2$

Step-by-step explanation:

First start by finding the slope of the segment that joins those two points using the general formula for the slope of the segments between two points $(x_1,y_1)$ and $(x_2,y_2)$ on the plane:

$Slope=\frac{y_2-y_1}{x_2-x_1}$

Then for our case, calling (-4, 6) = $(x_1,y_1)$ and (-8, 10) = $(x_2,y_2)$ , we have:

$Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{10-6}{-8-(-4)}\\Slope=\frac{4}{-8+4}\\Slope=\frac{4}{-4}\\Slope= -1$

Now, knowing this, we can find the equation of the line by using the "point-slope" form of a line [of slope "m" and going through the point $(x_0,y_0)$ that tells us:

$y-y_0=m(x-x_0)$

We will be then using the found slope (-1) and for example one of the given points: (-4 , 6), thus:

$y-y_0=m(x-x_0)\\y-6=-1(x-(-4))\\y-6=-1(x+4)\\y-6=-x-4\\y=-x-4+6\\y=-x+2$

If x= -8 and y=-4, evaluate the expression.<br> <img src="https://tex.z-dn.net/?f=%5Cfrac%7B3x-4%7D%7By-3%7D" id="TexFormula1"

bagirrra123 [75]

Your answer would be 4.

If we substitute in x = -8 and y = -4 into the expression, we get:

$\frac{3(-8) - 4}{-4 - 3}$

This then becomes:

$\frac{-24 - 4}{-7}$ = $\frac{-28}{-7}$ = 4.

I hope this helps!

Mrs Larsen made 12 pillows from 16 yards of the same fabric. How much fabric was used to make each pillow? between what two whol

Zepler [3.9K]

Yards per pillow.....yds/pillow....make sure u put the yds over the pillows when dividing

16/12 = 1.33 (or 1 1/3) yds per pillow....this lies between 1 and 2 yds

24,000,000 because 600,000 is more than 1/2 1,000,000 so you round up.
