Answer:
Step-by-step explanation:
Use the slope formula:
where m = slope
Given the coordinates
(-4, 4) ---> this means x1 = -4 , y1 = 4
(2, -5) ---> this means x2 = 2 , y2 = -5
Substitute these values into the slope formula:
Answer:
3:4 or 30:40
Step-by-step explanation:
basically means 30 blue pieces for every 40 green pieces
The customer gave me:
-- a ticket worth $5
-- a ticket worth $2
-- a bill worth $100
Total. . . . . . .$107
I gave him:
-- some gas worth $17.01
-- a ticket worth $ 5
-- two $1 tickets $ 2
-- a ticket worth $ 3
Total. . . . . . . .$27.01
The total value of everything we trade has to be equal.
I owe him ( $107.00 - $27.01 ) = $79.99 in change
