A line contains the points (-15,-8) and (9,13). Find the y-value of the y-intercept. For example, if the y-intercept is (0,1/3), record 0.33.
9.
Write your answer solution rounded to two decimal places.

The y-intercept is 5.12 or (0, 5.12)

Step-by-step explanation:

Use the two given points to find the slope

(-15, -8) (9, 13)

The use the slope and one of the given points to solve the slope-point formula

The y-intercept is which is equivalent to 5.125

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:
