Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

14 < -2a + 6 - 2a

• a > -2
• a < -2
• a > 2
• a < 2

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

What is the first step in solving the following equation for v?
7v + 15 = 4(5v + 7)

• Distribute 4:    7v + 15 = 20v + 28
• Distribute 4:  7v + 15 = 20v + 7
• Subtract 5v:  2v + 15 = 4(7)
• Subtract 7v:   15 = 4(-2v + 7)

Write an inequality for the graph:

• x > -2
• x < -2
• x ≥ -2
• x ≤ -2

What type of association does this scatter plot represent?

• positive linear association
• negative linear association
• no association
• nonlinear association

Solve by elimination 
5x+6y= -10
3x-2y= -6

• (-2,0)
• (0,-2)
• (2,0)
• (0,2)

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)
