Step-by-step explanation:

Use two ordered pairs from the table to find the slope  of f(x):

(-4, - 9) and (6, 6)m = (6 - (-9)) / (6 - (-4)) = 15/10 = 1.5

Find the equation of f(x) using point-slope form:

y - y₁ = m(x - x₁)y - (- 9) = 1.5(x - (-4))y + 9 = 1.5(x + 4)

The y-intercept is the value of y when x = 0:

y + 9 = 1.5*4y + 9 = 6y = - 3

Use two points on the graph and find the slope of g(x):

(0, 4) and (1, - 3)m = (- 3 - 4) / 1 = - 7

Find the required sum:

- 3 + (- 7) = - 10

You have to give us options

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
