14. Find the slope of a line parallel to 3y - 6x = 9. (Lesson 3-4)
DanielleElmas [232]

\bf 3y-6x=9\implies 3y=6x+9\implies y=\cfrac{6x+9}{3}\implies y = \cfrac{6x}{3}+\cfrac{9}{3} \\\\\\ y = \stackrel{\stackrel{m}{\downarrow }}{2}x+3\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}

a parallel line to that one above, will have the same exact slope, since parallel lines have the same slope.

What are rational numbers
Sophie [7]
A rational number is a number that can be written as a fraction or "ratio".
It includes the set of integers because all of them have a denominator of 1.  A rational number can take on the form of \frac{a}{b} where b ≠ 0.  Terminating and repeating decimals are rational numbers because they too can be written as a ratio; for example, 0.3 = \frac{3}{10} or 0.3333... = \frac{1}{3}.
