Answer:
The total number of branches = total possibilities = the denominator of a probability.
So the second choice is correct.
Let me know if this helps!
x=2/5, y=-24/5. (2/5, -24/5).
Step-by-step explanation:
y=-2x-4
y=1/2x-5
----------------
-2x-4=1/2x-5
-2x-1/2x-4=-5
-4/2x-1/2x=-5+4
-5/2x=-1
5/2x=1
x=1/(5/2)
x=2/5
y=1/2(2/5)-5
y=1/5-5
y=1/5-25/5
y=-24/5
