Answer:
 -5
Step-by-step explanation:
 There is different ways to solve methods of elimination but if you wanted to cancel y out you would multiply by the opposite sign....for example 
7x + 5y = 19
-5 (2x + y = 19) ---> -10x -5y = 95 
this would cancel out your y to solve for x so you can plug it back in and solve! hope this helps!!!

Answer:
y =  x - 1
 x - 1
Step-by-step 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 =  , then
 , then
y =  x + c ← is the partial equation
 x + c ← is the partial equation
To find c substitute (- 4, - 7 ) into the partial equation
- 7 = - 6 + c ⇒ c = - 7 + 6 = - 1
y =  x - 1 ← equation of line
 x - 1 ← equation of line
