Select the correct answer.
which set of vertices forms a parallelogram?
a.
a(2, 4), b(3, 3), c(6, 4), d(5, 6)
b.
a(-1, 1), b(2, 2), c(5, 1), d(4, 1)
c.
a(-5, -2), b(-3, 3), c(3, 5), d(1, 0)
d.
a(-1, 2), b(1, 3), c(5, 3), d(1, 1)

OPTION C.

Step-by-step explanation:

A parallelogram is defined as a quadrilateral which has two pairs of parallel sides.

Attached is shown in the parallelogram obtained by plotting the vertices provided in Option C.

If that figure is a parallelogram, then:

Let's check this:

Therefore, the set of vertices that forms a parallelogram is:

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
