Enter the equation of the line in slope-intercept form. Slope is -1/2, and (-9,4) is on the line. The equation of the line is y=

dezoksy [38]

Answer:

$y=\displaystyle-\frac{1}{2}x-\displaystyle\frac{1}{2}$

Step-by-step explanation:

Hi there!

Slope-intercept form: $y=mx+b$ where <em>m</em> is the slope and <em>b</em> is the y-intercept (the value of y when x is 0)

<u>1) Plug in the slope (</u><u><em>m</em></u><u>)</u>

We're given that the slope is $\displaystyle-\frac{1}{2}$ . In $y=mx+b$ , replace <em>m</em> with $\displaystyle-\frac{1}{2}$ :

$y=\displaystyle-\frac{1}{2}x+b$

<u>2) Determine the y-intercept (</u><u><em>b</em></u><u>)</u>

$y=\displaystyle-\frac{1}{2}x+b$

We're given the point (-9,4). Plug this point into the equation as $(x,y)$ and solve for <em>b</em>:

$4=\displaystyle-\frac{1}{2}(-9)+b\\\\4=\displaystyle\frac{9}{2}+b$

Subtract $\displaystyle\frac{9}{2}$ from both sides to isolate <em>b</em>:

$4-\displaystyle\frac{9}{2}=\displaystyle\frac{9}{2}+b- \displaystyle\frac{9}{2}\\\\\displaystyle-\frac{1}{2} = b$

Therefore, the y-intercept is $\displaystyle-\frac{1}{2}$ . Plug this back into $y=\displaystyle-\frac{1}{2}x+b$ as <em>b</em>:

$y=\displaystyle-\frac{1}{2}x+(\displaystyle-\frac{1}{2})\\\\y=\displaystyle-\frac{1}{2}x-\displaystyle\frac{1}{2}$

I hope this helps!

Where is the 1st quartile in this data set? <br><br> 36, 27, 15, 22, 33, 28, 43, 12, 33, 17

ziro4ka [17]

First of all, you have to rank the numbers from the lowest to the hightest. I let you to do it.

There are 10 numbers.

So, 0.25*10 = 2.5.

In that case, the 1st quartile would be the third number "17".

Hope this helps !

Imagine that you own a car that runs on alcohol made from corn that you grow. You drive your car about 15,000 miles in a year, a

ollegr [7]

So, said you drive your car 15,000m/year and you produce 250 gallon from each acre of corn you grow, your car use 1 gallon per 20miles.
15,000 m/year
250 gallons = 1 acee
20 Mile = 1 gallon
Total gallon = 15,000/20
Total gallon = 750
Since 1 acre is 250 gallons.
Total acre = 750/250
Total acre = 3
You need to have 3 acre to go 15,000 m/year.
