Which function has a y-intercept of 3?

If you have choices, you should list them. If you are just asking about any example, then here are some.

y = a*x + 3 ; the value of a can be any real number.

- 3x + y = 3
 2y + 4x = 6

ny = ax + 3*n When you divide through by n, you get
y = a/n * x + 3n/n
y = ax/n + 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
