Which equation represents the line that passes through points (2, 0) and (6, -8)?

$\bf (\stackrel{x_1}{2}~,~\stackrel{y_1}{0})\qquad (\stackrel{x_2}{6}~,~\stackrel{y_2}{-8}) ~\hfill \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{-8}-\stackrel{y1}{0}}}{\underset{run} {\underset{x_2}{6}-\underset{x_1}{2}}}\implies \cfrac{-8}{4}\implies -2 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{0}=\stackrel{m}{-2}(x-\stackrel{x_1}{2})\implies y=-2x+4$

you buy 5 pairs of jeans and 10 t-shirts for 140$.your friend buys 3 pairs of jeans and 5 t-shirts for $79. write and solve a sy

timurjin [86]

J = jeans

T = t-shirts

You: 5j + 10t = 140

Friend: 3j + 5t = 79

To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:

5j + 10t = 140

-6j - 10t = -158

We are left with -j = -18 or j = 18

Substitute 18 into any equation. I'll use the first equation:

5(18) + 10t = 140

90 + 10t = 140

10t = 50

t = 5
