Answer:
y = 
 x + 4
 x + 4
Explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 
 , thus
, thus
y = 
 x + c ← is the partial equation
 x + c ← is the partial equation
To find c substitute (- 2, - 1) into the partial equation
- 1 = - 5 + c ⇒ c = - 1 + 5 = 4
y = 
 x + 4 ← equation of line
 x + 4 ← equation of line
