<u>Using y = mx + b</u>

8y = 4x - 16  ⇒   y = \frac{1}{2}x - 2

-x = -2y - 4  ⇒  2y - x = - 4   ⇒   2y = x - 4   ⇒   y = \frac{1}{2}x - 2

Since the equations have the same slope (\frac{1}{2}x) and y-intercepts (-2), then they are the same line.  Thus, they intersect at every point so have infinite solutions.

Answer: A

Find cot θ if csc θ = negative square root of thirty seven divided by six and tan θ &gt; 0.
Ket [755]
You can use the trigonometric identity  1+\cot^2{x}=\csc^2{x}.

1+\cot^2{\theta}=(\frac{-\sqrt{37}}{6} )^2 \\ 1+\cot^2{\theta}=\frac{37}{36} \\ \cot^2{\theta}=\frac{1}{36} \\&#10;\cot{\theta}=\frac{1}{6}

The requirement that \tan{\theta}\ \textgreater \ 0 eliminates -1/6 from being another solution.
