step-by-step explanation:

when you realize that you dont know just realize i just took a test and im so smart

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

slope= 1

y-inter slope= 0

x       y

o     0

1       1

2     2

ect.
