Chapter 8 - Section 8.1 - Review of Equations of Lines and Writing Parallel and Perpendicular Lines - Exercise Set: 16


y+3=$\frac{5}{4}$(x-8) $\frac{5}{4}$x-y=13

Work Step by Step

(8;-3),(4,-8) m=$\frac{-8+3}{4-8}$=$\frac{-5}{-4}$=$\frac{5}{4}$ slope $\frac{5}{4}$ ,through(8;-3) y-$y_{1}$=m(x-$x_{1}$) y+3=$\frac{5}{4}$(x-8) y+3=$\frac{5}{4}$x-10 3+10=$\frac{5}{4}$x-y 13=$\frac{5}{4}$x-y
