What is the slope of the line that goes through (-5,5) and (5,-7)

y2-y1/x2-x1

=-7-5/5-(-5)

=-12/10

=-6/5

Step-by-step explanation:

Given two points on on a line to find the slope we use the formula y2-y1/x2-x1 , hence the answer above.

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:
