Answer

$y-5=3(x-9)$

Work Step by Step

With the given points, $ (9,5)$ and $(8,2),$ then \begin{align*} y_1&= 5 ,\\y_2&= 2 ,\\x_1&= 9 ,\text{ and }\\ x_2&= 8 .\end{align*} Using $m=\dfrac{y_1-y_2}{x_1-x_2}$ or the Slope Formula, the slope, $m,$ of the line connecting the two given points is \begin{align*} m&= \dfrac{5-2}{9-8} \\\\&= \dfrac{3}{1} \\\\&= 3 .\end{align*} Using $ y-y_1=m(x-x_1) $ or the Point-Slope Form, with $m= 3 $ and using the point $ (9,5) $, then \begin{align*} y-5&=3(x-9) .\end{align*} A Point-Slope Form of the line with the given conditions is $ y-5=3(x-9) .$
