Which set of values is a function?

• (9,5) (10,5) (9,-5) (10,-5)

• (3,4) (4,-3) (7,4) (3, 8)

• (6,-5) (7, -3) (8, -1) (9, 1)

• (2, -2) (5, 9) (5, -7) (1, 4)

For the function f(x) = -3x + 3 find f(0).

• 0

• -3

• 3

• -1

Given f(x) = -4x - 10 and f(x) = 10. Find x

• x = -5

• x = 5

• x = -50

• x = 30

Simplify this expression:

-7w + (-6) + 5 + (-9w)

• -2w - 1

• -16w - 11

• -16w - 1

• -2w + 11

½(10p - 7q) if p = 9 and q = 2

• 31

• 38

• 52

• 152

(20ab) ÷ (a-b)² if a = 4 and b = -2

• 40/3

• 40

• -40/9

• -13

Find the slope of the line that passes through
(10, 1) and (5, 2)

• 1/5

• -1/5

• 5

• -5

Give the slope and y-intercept
6x - 3y = -9

• slope is 6 
  y-intercept is 9

• m=2
  b=3

• slope is 2
  y-intercept is -3

• m = 3
  b = 2

Write the equation of a line in point slope form that goes through the points (4,7) and (5,1).

• y-7=-6(x-4)

• y+1=-6(x+5)

• y-7=-1/6(x-4)

• y-1=-1/6(x-5)

Use the equations given to determine if the following lines are parallel, perpendicular, neither or both.
y-2=.5(x+3)
y-4=.5(x-2)

• parallel

• perpendicular

• neither parallel nor perpendicular

• both parallel and perpendicular
