Answer with explanation:

It is given that pair of vertical Angles are Always Supplementary.

→Vertical Angle = Angle having measure of 90°

→Supplementary = Sum of two angles is 180°.

→Sum of two vertical Angle = A supplementary Angle

→90°+90°

=180°

⇒The term which Describes a pair of vertical angles that are always supplementary=Right

Option C

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

i think it would be c
