Answer:

Slope = [tex]\frac{-4}{3}[/tex]

4x + 3y = 23

Step-by-step explanation:

slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-3-5}{8-2} =\frac{-8}{6} =\frac{-4}{3}[/tex]

The equation:

[tex]\frac{y-y_{1} }{x-x_{1} }=m[/tex]   m is the slope

[tex]y-y_{1}=m(x-x_{1} )[/tex]

y - 5 = -4/3 (x - 2) Multiply both sides by 3

3y -15 = -4 (x - 2)  

3y - 15 = -4x + 8

3y + 4x = 8 + 15

3y + 4x = 23

4x + 3y = 23
