The two factors of a quadratic equation can be multiplied to form the original equation. Let the missing term be a:
y² + 15y + 56 = (y + 7)(y + a)
y² + 15y + 56 = y² + (7 + a)y + 7a
We can now compare the coefficient of the like terms, either the one with y or the one without y, and find the value of a.
15 = 7 + a; a = 8
OR
56 = 7a; a = 8
Second factor is (y + 8)
Yes because the results are unlikely to occur by chance, is what I think .

Answer:
3 is les than 3.58
Step-by-step explanation:
3 is less than 3.58
Answer:
you find the slope by putting the equation in slope intercept form y=mx+b
so you would subtract 2x and have 2y=-2x+8
then you would divide by 2 to get y be itself so
y=-x+8
So your slope is -1/1
