Find the constant of variation and the slope of the direct variation model y=2x

djyliett [7]

A direct proportional variation, is really just a slope-intercept form of equation, except that the y-intercept is always 0, and the constant of variation "k" is the slope pretty much.

$\bf \qquad \qquad \textit{direct proportional variation}\\\\
\textit{\underline{y} varies directly with \underline{x}}\qquad \qquad y=kx\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------\\\\
y=\stackrel{\stackrel{slope}{k}}{2}x\stackrel{y-intercept}{+0}\impliedby \stackrel{k}{2}\qquad \qquad \stackrel{slope}{\cfrac{2}{1}}$

Write four numbers that round to 700000 when rounded to the nearest hundred thousand

ruslelena [56]

you need to look at the number in the spot to the right of the hundred thousands place to determine what to do. If it is 4 or below, they all drop to 0. If it is 5 or above, they all drop to 0 and the hundred thousands place goes up by 1.

651000, 663200, 723000, 749999
