Answer asap! wait until i can edit this or i will report!

So intersection
first one we see that (2,0) is not one
(-1,0) is
(2,1) isn't
(-3,2) is'nt either
answer is B

2nd attachment
just subsitutte
try (2,2) in all of them
A, 2nd equation doesn't work
B. first equation doesn't work
C. first equation doesn't work
D. both work
D is answer

3rd attachment
distance=200 miles
so
w=water speed
s=boat speed in still water
d=st

upstream is with the water helping
downstream is wht water against
so
200=5(s+w)=4(s-w)

200=5(s+w)
divide by 5
40=s+w

other one
200=4(s-w)
dvde by 4
50=s-w

we gots

40=s+w
50=s-w
add them equations
90=2s
divide by 2
45=s

answer is C

4th attachment
see intersection
at x=2 and y=3 so (2,3)
D is answer

5th attachment
that is the horizontal line
that is y=3
erm
the equation of the other line is y=3x-3
so if y=3
3=3x-3
C is answer
