Answer:

  • - 20.5

Step-by-step explanation:

Given two points on the line:

  • (86, 78) and (90,-4)

Use the slope equation:

  • m = (y₂ - y₁)/(x₂ - x₁)
  • m = (-4 - 78)/(90 - 86) = - 82/4 = - 20.5
  • (86,78)
  • (90,-4)

Slope:-

[tex]\sf\longmapsto m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\sf\longmapsto m=\dfrac{-4-78}{90-86}[/tex]

[tex]\sf\longmapsto m=\dfrac{-82}{4}[/tex]

[tex]\sf\longmapsto m=-41/2[/tex]

[tex]\sf\longmapsto m=20.5[/tex]
