idk this answer sorry cant on this one.

step-by-step explanation:

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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
