Answer: y=-8/10x+29

Step-by-step explanation:

1. choose 2 points on form the chart

  • (10,21)(20,13)

2. y2-y1/x2-x1

  • 13-21/30-10=-8/10

3. y-y1=m(x-x1)

  • y-21=-8/10(x-10)

4. multiply

  • y-21=-8/10(x-10)
  • y-21=-8/10x+8

5. you need to isolate the variable so..

  • y-21=-8/10x+8
  • +21             +21

       y=-8/10x+29
