Step-by-step explanation:

That is what she means! I don't know what you're asking but this may help the people that want to answer this question. :)

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

you start with 40 minutes and 8 people to paint a wall. then it asks how many minutes does it take 10 people to paint seven walls.

that means you start with division.

40÷8=5

10×5=50

now you want to multiply the amount of walls by number minutes.

50*7= 150 minutes or 2½hrs

hope this ! -john
