Y-y1=m(x-x1)
for slope=m
a point =(x1,y1)
slope=2
point= (-1,3)
y-3=2(x+1)
y-3=2x+2
y=2x+5
test given points
A.
(1,5)
5=2(1)+5
5=7
false
B.
(1,4)
4=2(1)+5
4=7
false
C.
(-3,2)
2=2(-3)+5
2=-6+5
2=-1
false
D.
(0,5)
5=2(0)+5
5=0+5
5=5
true
answer is D
This is a polynomial of degree 4, because you have 4 roots real or imaginary:1st) x= 5 →(x-5)=0
2nd) x = - 3→(x+3) =0
3rd) x = -1+3i →(x+1-3i) = 0
and the 4th one that is not mentioned which is the conjugate of
-1+3i, that is -1-3i (in any polynomial if a root has the form of a+bi, there is always a conjugate root = a-bi)
4th) x= -1-3i→(x+1+3i) = 0
Hence the polynomial =(x-5)(x+3)((x+1-3i)(x+1+3i)
Solving the above will give you (unless I am mistaken, pls recalculate):
x⁴-9x²-50x-150<u />
Answer:
Translation is 67x-65=x-4, you can use any variable for the number.
