Complete the point slope equation of the line through (-8,-8) &' (-7,9) y-9=
hram777 [196]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ -8 &,& -8~) 
%  (c,d)
&&(~ -7 &,& 9~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{9-(-8)}{-7-(-8)}\implies \cfrac{9+8}{-7+8}
\\\\\\
\cfrac{17}{1}\implies 17
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y- y_2= m(x- x_2)}\implies y-9=17[x-(-7)]
\\\\\\
y-9=17(x+7)

The equation below could be used to solve which of the following problems?
Rina8888 [55]
The answer is A. Twenty-five is 65% of what number?
Why? This is due to how if you multiply 'w'(the number) by 0.65(65%) then you get 25. This indicates that whatever the number is, if it is multiplied by 65% it equals 25. Thus concluding that 25 is 65% of the unknown number.

I hope that helps, have a great rest of your day! ^ ^
