Answer:

[tex]y=-\frac{2}{5}x +8.4[/tex]

Step-by-step explanation:

Gradient

[tex]m =\frac{y-y1}{x-x1}[/tex]

[tex]m = \frac{6-4}{3-8}[/tex]

[tex]m=-\frac{2}{5}[/tex]

Equation of a line

[tex](y-y1)=m(x-x1)\\[/tex]

- Sub one set of points into equation

[tex](y-6)= -\frac{2}{5} (x-6)[/tex]

[tex]y=-\frac{2}{5}x +8.4[/tex]
