Since I can't see the graph, I can't choose exactly, but if:

1. as x rises, y falls

and

2. there is no one slope (there is one curve)

then it represents exponential decay.

Aka. it's a downward woosh.

Answer:

⁻ $\frac{19}{3}$

Step-by-step explanation:

⁻ $9 + \frac{2}{3} (1+1)^{2}$

⁻ $9 + \frac{2}{3}$ × $2^{2}$

⁻ $9 + \frac{2}{3}$ × $4$

⁻ $9$ $+$ $\frac{2 x 4}{3}$

⁻ $9 + \frac{8}{3}$

⁻ $\frac{19}{3}$

Answers:

Rate of change = -5

Initial value = 25

Step-by-step explanation:

Each time x increases by 2 (eg from x = 1 to x = 3), the value of y drops by 10 (eg from y = 20 to y = 10)

Therefore the slope is...

slope = rise/run = (change in y)/(change in x) = -10/2 = -5

slope = -5

So each time x increases by 1, y will decrease by 5

Flip things around: each time x decreases by 1, y will increase by 5

So the pair (x,y) = (1,20) shown in row 1 of the table leads to (0,25) based on the rule above. Another way to see this is to plug m = -5, x = 1 and y = 20 into y = mx+b and solve for b to get b = 25
