Answer 15

Okay.

line 1:
m = dy/dx
m = (6 - 3)/(3 + 6)
m = 3/9
m = 1/3
y - 6 = (1/3)(x - 3)
y = (1/3)x - 1 + 6
y = (1/3)x + 5
---
line 2:
m = dy/dx
m = (3 - 1)/(3 + 3)
m = 2/6
m = 1/3
y - 3 = (1/3)(x - 3)
y = (1/3)x - 1 + 3
y = (1/3)x + 2


---
the lines are parallel (equal slopes), but distinct (different y-intercepts) ...
the linear system has no solutions
---
answer:
A. 0
