Answer:

Since there are two points there are two equations that can written.

1.
y-7=-(1)/(3) (x+4)

2.
y-3=-(1)/(3) (x-8)

Explanation:

Step 1: Point Slope Form


  • y-y_(1) =m(x-x_(1))

Step 2: Find the slope of the two points

  • Slope = m

  • m=(y_(2)-y_(1))/(x_(2)-x_(1))
  • Points: (-4,7) and (8,3)
  • y₂ = 3
  • y₁ = 7
  • x₂ = 8
  • x₁ = -4

  1. m=(3-7)/(8-(-4))=(-4)/(8+4) =(-4)/(12) =(-1)/(3)

Step 3: Write the equation


  • y-y_(1) =m(x-x_(1))

  • m=-(1)/(3)
  • Points: (-4,7) and (8,3)
  1. Using the point (-4,7):

  • y-7=-(1)/(3) (x+4)
  1. Using the point (8,3):

  • y-3=-(1)/(3) (x-8)
