The first 4 terms in a patter are shown below:
-10, -2, 6, 14, ...
If the pattern continues which expression can be used to find the nth term?

• 8n - 18

• -10n - 8

• -8n + 10

• 8n + 18

Mrs. Tafolla graphs the function f (x) = x and

g (x) = f (x) -10 on the same coordinate grid. How are the graphs of f and g are related.

• The graph of f is shifted down 10 units to create the graph of g.

• The graph of f is steeper than the graph of g.

• The graph of f is less steep than the graph of g.

• The graph of f is shifted up 10 units to create the graph of g.

Solve the equation:

5x - (5 - 2x) + 10 = 2x + 3(2x - 2)

• x = 11

• x = 1

• x = -11

• x = -1

Solve for y.

• y = -5.6

• y = 5.6

• y = -8.75

• y = 8.75

What is the x and y intercept for the following equation ?
4x - 10y = 20

• x - int = 4    
  y-int = -10
• x-int = 5
  y-int = 2
• x - int = 5
  y int = -2
• x -int = 4
  y -int = -10
