Answer:
B=-5
Step-by-step explanation:
Slope=rise/run
The line passes in
P1(-1,3)
and
P2(0,-2)
So slope=(3-(-2))/(-1-0)=5/-1=-5
(5,0) and (10,-10) is on the line and (5,0) is not so the answer is (5,0)
If this is the case, then you know by the polynomial remainder theorem that
is a factor of
, so there is some polynomial
such that
You can use proportions in all of these as I explained in another one of your questions. I'll post the answers if you still want them.
