Ax+by=c is form
start from y=mx+b form
we know that b=y intercept or b in (0,b) when x=0
so
we got (0,-4)
so b=-4
y=mx-4
find m
(5,1)
x=5 and y=1 is true
1=5m-4
add 4 both sides
5=5m
divide 5
1=m
slope is 1
y=1x-4
y=x-4
convert
minus x both sides
-x+y=-4
times -1
x-y=4
I believe it's C. Mainly answering so you can give out Brainliest, good luck on your test.
Answer:
D
Step-by-step explanation:
Y²+7y+10/y²-25 this is the equation now if your looking for the answer it would be
y^4+7y^3-25y^2-175y+10

(y+5)(y-5)
sorry if is a little messy
