Answer:

  • y = - x + 2

Step-by-step explanation:

Points given:

  • (-1, 3), (1, 1), (3, -1), (5, -3)

Slope-intercept form:

  • y = mx + b

Finding the slope using slope formula and the first two points:

  • m = (1 - 3)/(1 - (-1)) = -2 / 2 = -1

Finding y-intercept using the slope and the first point:

  • 3 = (-1)*(-1) + b
  • 3 = 1 + b
  • b = 3 - 1
  • b = 2

So the equation is:

  • y = - x + 2
