Short Answer: Yes.

I can't think of any that are not. Some go out a pretty long ways before they repeat, but they are still rational. I use a rather limiting definition for rational numbers. If you know which digit you are on, you can tell what the next digit will be. For example, If you have a repeating decimal like
0.2334445523344455... and you are told what the 100th digit is, you will be able to claim you know what the 101st digit is. It may not be a simple calculation, but it can be done.

Answer:

$y=\frac{2}{3}x-6$

Step-by-step explanation:

Use the slope-intercept form:

$y=mx+b$

m is the slope and b is the y-intercept. Looking at the graph, you can find the y-intercept. The y-intercept is the point where x equals 0:

$b=-6$

$y-intercept=(0,-6)$

To find the slope, take any two points from the line:

$(6,-2)(3,-4)$

Use the slope formula for when you have two points:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{rise}{run}$

The rise over run is the change in the y-axis over the change of the x-axis. Insert the appropriate values:

$(6(x_{1}),-2(y_{1})\\(3(x_{2}),-4(y_{2})$

$\frac{-4-(-2)}{3-6}$

Simplify parentheses (two negatives makes a positive):

$\frac{-4+2}{3-6}$

$\frac{-2}{-3}$

Simplify (two negatives make a positive):

$m=\frac{2}{3}$

The slope is $\frac{2}{3}$ and the y-intercept is $-6$ . Insert these into the equation:

$y=\frac{2}{3}x-6$

Finito.

Step-by-step explanation:

pythagreom theroem

c (hypotenuse) = $\sqrt{a^{2} +b^{2} }$

plug in values for a and b

c= $\sqrt{6^{2} +8^{2} }$

c= $\sqrt{36+64\\}$

c= $\sqrt{100\\}$

c=10
