<u>Answer with step by step explanation</u>
To find the equation of the line from the given equation, you have to make y as the subject in the equation.
<u>Let us find now.</u>
x + 3y = -4
3y = -4 - x
3y = -x - 4
<em>Divide the whole equation by 3.</em>
y = -x/3 - 4/3
Therefore, <u>the equation of the line</u> is:
<u> y = -x/3 - 4/3</u>
And now we have to find the slope and the y - intercept of the line.
That is, we have to find the m & c of y = m x + c.
Here,
m ⇒ slope
c ⇒ y - intercept
So, to find it we have to find the values which were replaced with m & c.
<u>Let us find now.</u>
y = m x + c
y = <u>-x/3</u> <u> - 4/3</u>
Now it is clear that, <u>-1/3 & -4/3 are replaced with m & c</u> respectively.
Therefore,
slope ⇒<u> -1/3</u>
y - intercept ⇒<u> -4/3</u>

Answer:
3 2/5
I converted these into decimals, because I find it easier ^.^
We have an 8 feet board, and we twice remove 2 1/3 from that number.
8 - 2 1/3 = 5.7
5.7 - 2 1/3 = 3.4 or 3 2/5
~Hope this helps~
The new perimeter will be 3 times the old perimeter.
Original perimeter:
2(8+7) = 2(15) = 30 yds
New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds
30 x 3 = 90
