Solve the problem.
-Find the equation of the line $y = a x + b$ that passes through the points $( - 1,4 )$ and $( - 5 , - 6 )$

A) $y = \frac { 13 } { 2 } x + \frac { 5 } { 2 }$

B) $y = \frac { 1 } { 2 } x + \frac { 7 } { 2 }$

C) $y = \frac { 5 } { 2 } x + \frac { 13 } { 2 }$

D) $y = \frac { 1 } { 2 } x + \frac { 4 } { 9 }$
