The number of miles, x, that a cross country athlete can run is represented by the inequality
X + 3 < 15
What conclusion can be made about the number of miles?
Select one:

A. The runner can run more than 12 miles

B. The runner can run 12 miles

C. The runner can run 15 miles

D. The runner can run less than 12 miles

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.

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
