Which is the equation of a trend line that passes through the points (3, 95) and (11, 12)? Round values to the nearest ten-thous

Nookie1986 [14]

<h2>Answer:</h2>

The equation of trend line is:

$y=-10.3750x+126.1250$

<h2>Step-by-step explanation:</h2>

We know that a equation of a line that passes through two points (a,b) and (c,d) is given by:

$y-b=\dfrac{d-b}{c-a}\times (x-a)$

Here we have:

(a,b)=(3,95) and (c,d)=(11,12)

Hence, the equation of the line is:

$y-95=\dfrac{12-95}{11-3}\times (x-3)\\\\\\y-95=\dfrac{-83}{8}\times (x-3)\\\\\\y-95=\dfrac{-83}{8}x+\dfrac{83}{8}\times 3\\\\\\y=\dfrac{-83}{8}x+\dfrac{249}{8}+95\\\\\\y=\dfrac{-83}{8}x+\dfrac{1009}{8}\\\\\\y=-10.3750x+126.1250$
