Which is the graph of y= -x + 2?

• A

• B

• C

• D

• x = -4
• x = 4
• x = -3
• x = 3

Find the slope  and y-intercept of:

2x - 3y = -12

• slope = 2/3, y-intercept = -12

• slope = -2/3, y-intercept = -3

• slope = 2/3, y-intercept = 4

• slope = -12, y-intercept = -3

Evaluate f(-4) for the function f(x)=3x²-5

• f(-4) = 43

• f(-4) = 139

• f(-4) = -52

• f(-4) = -149

What is the slope:

5x + 10y  = 30

• m = -1/2

• m = 1/2

• m = 3

• m = 1/3

Which inequality is represented in the graph below?

• y ≥ −3x + 4

• y ≤ 3x + 4

• y ≥ −4x − 3

A cell phone company charges $60.00 a month for up to 1 gigabyte of data. The cost of additional data is $0.05 per megabyte. If d represents the number of additional megabytes used and c represents the total charges at the end of the month, which linear equation can be used to determine a user's monthly bill?  

• c = 60 - 0.05d

• c = 60.05d

• c = 60d - 0.05

• c = 60 + 0.05d

The owner of a small computer repair business has one employee, who is paid an hourly rate of $22. The owner estimates his weekly profit using the function P(x) = 8600 − 22x . In this function, x represents the number of

• computers repaired per week

• hours worked per week

• customers served per week

• days worked per week

Solve for x
32 - x = -3(x - 4)

• x = -10

• x = -16

• x = -18

• x = -22

Find slope:

• m= 4

• m=1/4

• m=-4

• m=-1/4
