A.
Note that 1 mile = 1.609 km.
Therefore
0.6 miles = 0.6*1.609 km = 1 km (approximately).
b.
Note that 1 US quart = 0.9463 liters.
Therefore
1 quart = 1 liter (approximately).
c.
Note that 1 pound = 0.4536 kg
Therefore 1 pound is not even approximately equal to one kilogram.
d.
Note that 1 yard = 0.9144 m.
Therefore
1 yard = 1 m (approximately).
Answer:
1 pound is not approximately equivalent to one of the metric units.
I like point point form because it doesn't fail in the no slope case. The line through (a,b) and (c,d) is
(c-a)(y-b) = (d-b)(x-a)
Point slope form is almost the same,

1. (a,b)=(4,0),(c,d)=(-2,1)
y - 0 = (1 - 0)/(-2 - 4) (x - 4)
Answer: y = (-1/6)(x-4)
2.
y - -2 = (3 - -2)/(5 - -3) (x - -3)
Answer: y + 2 = (5/8) (x+3)
3.
y - 1 = (4 - 1)/(3 - -5) (x - -5)
Answer: y - 1 = (3/8) (x+5)
The minimum is 91. The first quartile is 112. The median is 173. The third quartile is 215. The maximum is 253.
The answer to fill in the blank should be ''Linear''.
