Answer:

[tex]-\dfrac{1}{2}[/tex]

Step-by-step explanation:

Slope Formula

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Where (x₁, y₁) and (x₂, y₂) are points on the line.

Given points:

  • (x₁, y₁) = (8, 3)
  • (x₂, y₂) = (12, 1)

Substitute the given points into the formula and solve for m:

[tex]\implies \textsf{slope}\:(m)=\dfrac{1-3}{12-8}=\dfrac{-2}{4}=-\dfrac{1}{2}[/tex]

Therefore, the slope of the line for the path of the track is -¹/₂.
