Answer:

Step-by-step explanation:

(-3,14)  ; (6 , -1)

x₁ = -3   ; y₁ = 14

x₂ = 6   ;  y₂ = -1

[tex]Slope = \dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\\=\dfrac{-1-14}{6-[-3]}\\\\\\=\dfrac{-15}{6+3}\\\\=\dfrac{-15}{9}\\\\\\m=\dfrac{-5}{3}[/tex]

Slope intercept form: y = mx +b

y = (-5/3)x + b

Plugin x = -3 and y = 14

[tex]14 = \dfrac{-5}{3}*(-3)+b\\\\14=5+b\\\\\\14 -5 = b\\\\b = 9[/tex]

Slope intercept form:

[tex]y=\dfrac{-5}{3}x +9[/tex]
