Answer:

  • y = -3x + 7

Step-by-step explanation:

Use points on the graph:

  • (0, 7) and (2, 1)

Find the slope:

  • m = (1 - 7)/ 2 = -3

The y-intercept is known b = 7, so the equation is:

  • y = mx + b
  • y = -3x + 7
  • (1,4)
  • (0,7)

Slope

  • m=7-4/-1
  • m=3/-1
  • m=-3

Equation

  • y-y1=m(x-x1)
  • y-4=-3(x-1)
  • y-4=-3x+3
  • y=-3x+7
