Answer:

The answer is -3

Explanation:

Slope = Rise/Run = Change in y/Change in x

Slope = (-4 - 8) / (3 - -1)

= -12/4

= -3

So, the answer is -3

Hope this helps! :)

Answer:

The slope of the line through (-1, 8) and (3, -4) = m = -3

Explanation:

Given the points

  • (-1, 8)
  • (3, -4)

Determining the slope between (-1, 8) and (3, -4)

  • (x₁, y₁) = (-1, 8)
  • (x₂, y₂) = (3, -4)

Using the formula

Slope = m = [y₂ - y₁] / [x₂ - x₁]

= [-4 - 8] / [3 - (-1)]

= [-12] / [3+1]

= -12/4

= -3

Thus, the slope of the line through (-1, 8) and (3, -4) = m = -3
