Order the function from the least steep slope to the steepest slope. y = 4x + 0.5
y = x+42
y=-0.5x + 7
y = -2x + 3

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8

These are the multiples of 15 but what you are probably asking or what are the factors of 15
