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.

Answer:
in about 8 2/3 years
Step-by-step explanation:
The population difference of 13000 people is being erased at the rate of 1500 people per year. It will be gone in ...
13000/1500 = 26/3 = 8 2/3 . . . . years
The population of Lakeside will be 45000 -8667 = 36333 at that time. Eastside's population will be the same.
Eastville and Lakeside will both have populations of 36,333 in 8 2/3 years.
Answer:
The slope would be -2 with a y-intercept of (0, -3).
