Given the system of equations :

The shown represents the both equations
So, the equations will have the same description
The first equation :
y = -3 ( x + 2 )
y = -3x - 6
Which will be the same as the second equation
so, as shown the slope of both will be the coefficient of x = -3
And y- intercept for both will be = -6
so, the answer is the first option:
