Answer:

y=-2/7x+1

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-5-(-1))/(21-7)

m=(-5+1)/14

m=-4/14

simplify

m=-2/7

y-y1=m(x-x1)

y-(-1)=-2/7(x-7)

y+1=-2/7(x-7)

y=-2/7x+2-1

y=-2/7x+1

Marguerite is building a box from strips of wood.she needs 78 pieces of wood that are each 29 centimeters long.the wood comes in

dolphi86 [110]

Each strip is 29 cm

------------------------------------------------------
Change the m to cm
------------------------------------------------------
6 m = 600 cm

------------------------------------------------------
Find the number of strips for 1 6m-board
------------------------------------------------------
Find the number of strips that can be cut from the 6m board.

600 ÷ 29 = 20 pieces remainder 20cm

So we can only cut 20 pieces of 29 strips from one 6m board.

------------------------------------------------------
Find number of boards needed
------------------------------------------------------
70 ÷ 20 = 3.5

We need 3.5 of the 6m boards.

Since she can't have half a board, she has to buy 4 pieces of the board.

------------------------------------------------------
Answer: 4 pieces of the 6m board.
