y = -4x - 7 is asking me to solve by substitution and determine whether
y = 3x the equation is independent, dependent or inconsistent
----------------------------
If you get a one point intersection, the system is independent.
Substituting you get:
3x = -4x-7
7x = -7
x = -1
----
If x = -1, y = 3*-1 = -3
---------------
The point of intersection is (-1,-3)
The system is independent.
