Hey there!!! Since you are new here, read this legendary tutorial for new OpenStudiers!! http://goo.gl/5pp1u0

@Algebramakesmesad @~ :D :D

So basically you were given the point \(\sf (1,-5)\) and two equations:

\(\sf x + 2y = -9\)
\(\sf x - y = 6\)

So basically plug in:
\(\sf x = 1\)
\(\sf y =-5\)

and if those values work for both equations, your answer is true. If it does not, then the answer is false.
