Pls help I can't afford to fail. Complete the equation of the line whose y intercept is (0,-1) and slope of 4​

y = 4x - 1

Step-by-step explanation:

y + 1 = 4(x + 0)

y = 4x -1

y = 4x - 1

Step-by-step explanation:

All you want to do is put the equation into the form y = mx + b where m is the slope and b is the y-intercept (an example would be y = 2x + 1 which would have 2 is the slope and 1 is the y-intercept)

Since you have:

slope or m = 4

y-intercept or b = -1

The equation would be y = 4x - 1

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:

3+x
