Which of the following is the function form (slope intercept form) of the explicit formula an = 15 - 3(n - 1)?
f(n) = 3n - 18
f(n) = 3n + 18
f(n) = 18 - 3n
f(n) = 18 + 3n
Can all arithmetic sequences be modeled by a linear function?
No, because arithmetic sequences have a variable rate of change.
No, because linear functions have a variable rate of change.
Yes, because arithmetic sequences have a constant rate of change.
Yes, because linear functions have a constant rate of change.
Which of the following sequences represents a linear function?
-8, -6, 2, 8
-6, 1, 2, 8
-16, -2, 12, 26
-8, -6, -4, -1
What is the average rate of change for the table?
5 kilometers per minute

Gina has saved $300. She plans to save an additional $15 each week. Write an equation in explicit form.
s(t) = 315 + 15(n-1)
s(t) = 300 + 15(n-1)
s(t) = 300+15t
s(t) = 15t+300
Gina has saved $300. She plans to save an additional $15 each week. What is the function that describes Gina's savings as a function of time in factored form?
s(t) = 15(t + 300)
s(t) = 15(t + 20)
s(t) = 15(t -300)
s(t) = 15t+300

y-3=-2(x+4)
y + 2 = -3(x - 5)
Write the following equation in slope intercept form:
y - 5 = 3 ( x + 2 )
y = 3x + 8
y = 3x + 11
y = 3x + 1
y = 3x - 8
Write the following equation in slope intercept form:
y + 9 = 3(x - 1)
y = 3x + 12
y = 3x - 12
y = 3x - 6
y = 3x + 6
12x + 9
