(\stackrel{x_1}{-2}~,~\stackrel{y_1}{-6})\qquad \qquad \stackrel{slope}{m}\implies 4 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-6)}=\stackrel{m}{4}(x-\stackrel{x_1}{(-2)})\implies y+6=4(x+2)

y+6=4x+8\implies y=4x+2\impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

if y varies inversely as x and y = 194 when x = -13, find y when x = 50. Round your answer to the nearest hundredth, if necessar
pashok25 [27]

Step-by-step explanation:

Since, y varies inversely as x.

\therefore \: y =  \frac{k}{x}  \\ (k = constant \: of \: proportionality) \\   \therefore \: xy =  k...(1) \\ plug \: y = 194 \:  \: and \:  \: x =  - 13 \: in \: (1) \\ \therefore \:  - 13 \times 194=  k \\ \therefore \: k =  - 2522 \\ substituting \: k =  - 2522 \: in \: (1) \\ xy =  - 2522...(2) \\ this \: is \: equation \: of \: variation. \\ plug \: x = 50 \: in \: (2) \\ 50 \times y =  - 2522 \\  \therefore \:y =  \frac{ - 2522}{50}  \\   \huge \red{ \boxed{\therefore \:y =   - 50.44}}
