The answer to this is 20. You can find the length by using the formula l=a/w
Answer:
slope =
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (5, - 3) and (x₂, y₂ ) = (- 9, - 6)
m = = =
So if she makes 8 and hour and works 40 hours a week
