$\bf (\stackrel{x_1}{-2}~,~\stackrel{y_1}{8})\qquad
(\stackrel{x_2}{4}~,~\stackrel{y_2}{12})
\\\\\\
slope = m\implies
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{12-8}{4-(-2)}\implies \cfrac{12-8}{4+2}\implies \cfrac{4}{6}\implies \cfrac{2}{3}$

First of all the equation to find the slope between two points is y2 - y1 over x2 - x1. So, all plugged in, the equation would be 12 -8 over 4 - - 2 and you would end up with 4/6 as your slope.

<h3>Answer: False</h3>

Explanation:

The number $\pi$ (read out as "pi") is approximately 3.14

So $3 \times \pi = 3\pi \approx 3*3.14 \approx 9.42$

On the other hand,

$\sqrt{64} = \sqrt{8^2} = 8$

So we can see that the original claim is false because $3\times \pi \approx 9.42$ is <u>not</u> smaller than $\sqrt{64} = 8$ . It should be the other way around.
