If the equation y = 3x + 2 is changed to y = -3x + 2, how will the graph of the line change? a) it will shift down 3 units. b) it will shift left 1/3units. c) it will slope in the opposite direction. d) the new line will be parallel to the original line.

The 3  changes to -3 so the slope  will change to the opposite direction

C

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:
