Question

What is the slope indicated in the table below.

Answer 1

Answer: y=-8/10x+29

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
