WILL GIVE BRAINLIEST what is the rate of change of y=0.860x+3.302 if x=25?

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 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

The answer is D, 1/3

Step-by-step explanation:Slope=rise/run and in this case it rises 1 and goes right(runs) 3.
