Step-by-step explanation:

X1-y1
x2-y2
-4-3
0+30
-6
30
the answer would be -0.2
<span><span>The average rate of change formula is basically the slope formula, where you plug in: f(b)-f(a)/b-a. Then plug in the numbers. [f(0)=1,f(3)=7)]. So, 7-1/3-0. 6/3 is 2 so the average rate of change is 2. And that makes sense because the average rate of change is always the slope, and the slope is 2.</span></span>
As per the problem,
Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.
We have been asked to find , which expression can be used?
As per the distributive property , we know that

Now apply this on the given expression we get

Hence the expression , which can be used is 17(69+31)
