anonymous · Answer

The average rate of change is just the slope.

anonymous · Answer

$$\text{average rate of change}=\frac{y(3)-y(1)}{3-1}$$
$y(x)$ is the value of $y$ at a given $x$ value.

anonymous · Answer

$$\frac{ 800 - 900 }{ 3 - 0 }?$$

anonymous · Answer

It's y1 - y2 over x1 - x2

anonymous · Answer

So 900 - 850 over 0 - 1

anonymous · Answer

over 50 over -1
which is -50, which is our slope. Which is also our speed. :D

anonymous · Answer

The question says x1, and x3 though?

anonymous · Answer

It's on the same line, so it really doesn't matter.

anonymous · Answer

Okay! :D Glad I became a fan of you. xD

anonymous · Answer

850 - 750 over 1 - 3
100 over -2
100 / -2
-50
