Answer 1

(-11, -4) and (-9, -5)

First determine the slope
\[m =\frac{ (-5)-(-4) }{ (-9)-(-11) }\]
\[m =\frac{ -1 }{ 2 }\]
Now using the m value and one the given points find y = mx + b. Let's use (-9, -5).
\[-5=(\frac{ -1 }{ 2 })(-9)+b\]
\[-5=\frac{ 9 }{ 2 }+b\]
\[\frac{ -10 }{ 2 }-\frac{ 9 }{ 2 }+b\]
\[b =\frac{ -19 }{ 2 }\]
\[y =\frac{ -1 }{ 2 }x-\frac{ 19 }{ 2 }\] is the equation of the line.
