Can someone me answer this. i have to answer it asap

1) write an expression to represent the pattern.

19, 27, 35,

a) y = 11x + 8

b) y = 8x + 11

c) y = 19x

d) 8x = 11

2) write an expression to represent the sequence.

71, 62, 53,

a) y = 9x + 80

b) y = 9x + 71

c) y = -9x + 80

d) y = -9x + 71

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
