putting all points in equation of option B satisfies the table . so ans is option B
This is child's play.
So, basically:
Y=Length of foot
X= Length of your forearm.
This is simple. Your equation is Y=0.860x + 3.302
So, if you have a forearm (x) that is 17 inches long, then plug in x as 17. This leaves you to evaluate for Y.
New equation: Y=0.860(17) +3.302
Work it out, you get: Y=14.62 + 3.302
Work that out, you get: Y= 17.922 inches long.
And of course, Y is the foot.
So, your answer: If the forearm is 17 inches long, then the foot is 17.922 inches long. Simple.
So, part 2:
Rate of change. Well, you need slope then, because that's the same thing.
Y=mx+b, Where m=slope
Your answer turns to be 0.860 inches per length of arm, for rate of change.
Skipping the data, as that's only something you'd know.
Yes, it is indeed a function. There can't be any exponents greater than 1 on the placeholder, and it's obviously not a straight line if you plug it in.
So yeah, it's a function.

a). No. Variation in 'y' has no effect on 'x'.
b). No. Variation in 'x' has exactly the opposite effect on 'y'.
c). Yes. Variation in 'x' causes 'y' to vary 6 times as much in the same direction.
d). No. Doubling 'x' does not double 'y'.
