Y=mx+b
The m in this equation is equal to the slope of the function while the b equals the y-intercept. However, because the intercept is at zero, the b in the equation is excluded.
y=mx
Now in order to find the slope(m) of the equation, we will use the slope formula in order to find it. The slope formula is this:
(y2-y1)/(x2-x1)
So the slope formula when we use the points (1,8) and (2,16) is:
(16-8)/(2-1)=
8/1=
8
Now, that we have the slope, we can plug it into our equation:
y=8x
And there is your answer. Hope this helps you!

Answer:

The current area of the circle is 81π in².

They want to " 'decrease' " the radius to 9 in.

First, find the current radius for the current circle.

Areas of circle = πr²,

81π = πr²

First, divide π from both sides of the equation:

(81π)/π = (πr²)/π

r² = 81

Isolate the variable, r. Root both sides of the equation:

√(r²) = √(81)

r = √( 9 * 9) = 9

The radius currently is 9 in.

The NBA is not making any changes at all, therefore the question will be void. (Note that the other answer choice is -9, however, you cannot have a negative measurement, therefore, the answer is voided).
