For palarell lines, slope are equal.
slope of first line = (y2 - y1)/(x2 - x1) = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5
equation of a line passing through a point is given by: y - y1 = m(x - x1); where (x1, y1) = (-5, -15) and m = 4/5.
Therefore equation of the line is y - (-15) = 4/5(x - (-5))
y + 15 = 4/5(x + 5)

hoa [83]

I'm not too sure about this one but if you find 3% of $200 you get 6 and if you multiply that by 2 ( for the 2 years ) you'll get ( A $12 )

Find the percent of increase from 1.5 inches to 6 inches.

Komok [63]

Well, from 1.5 to 6 is a 4.5 difference.

now, if we take 1.5 to be the 100%, what is 4.5 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
1.5&100\\
4.5&p
\end{array}\implies \cfrac{1.5}{4.5}=\cfrac{100}{p}\implies p=\cfrac{4.5\cdot 100}{1.5}$
