if you are increasing till you get over 1,000

it would take 10.9 almost 11 years to get to 1,000

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function?

mamaluj [8]

Answer:

Option C. $y=(3/4)x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Find the value of the constant k

For the point (-8,-6)

$k=y/x=(-6/-8)=3/4$

For the point (12,9)

$k=y/x=(9/12)=3/4$

<u><em>Note</em></u> A single point was required to find the constant k (because the line passes through the origin)

The equation is equal to

$y=(3/4)x$

$\bf \begin{array}{ccccccccc}

% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{0-3}{4-0}\implies -\cfrac{3}{4}
