Convert the standard form equation into slope-intercept form.

4x + 3y = 15

• y = (4/3)x - 5

• y = ⅔x - 5

• x = ¾

• y = - (4/3)x + 5

Which graph represents x + y = 3

• A

• B

• C

• D

Select all which are solutions to the given inequality.

-3x + 2 > 8

• -2

• 2

• -5

• 0

• -10

What are the x and y intercepts of the graph.

• x-int: (4, 0)

  y-int: (0, 3)

• x-int: (0, 0)

  y-int: (0, -2)

• x-int: (-4, 0)

  y-int: (0, -3)

What is the equation of the line?

what is the slope intercept form for the equation -2x + 8y = 2

• y = -2x + 8

• y = 1/4x + 1/4

• y = -1/4x - 1/4x

• y = 2/8x + 4

1. The cost of 5 squash and 2 zucchini is $1.32. Three squash and 1 zucchini cost $0.75. Write a system of equation where q represents the price of one squash and z represents the price of one zucchini.

• 5q + 2z = 1.32

  1z = 0.75

• 5q + 2z = 1.32

  3q + 1z = 0.75

• q + z = 1.32

  q + z = 0.75

• 5q + 2z = 0.75

  3q + 1z = 1.32

On Monday Joe bought 10 cups of coffee and 5 doughnuts for his office at the cost of $16.50. . On Tuesday he bought 5 cups of coffee and 10 doughnuts for a total of $14.25. If c represents the price of a cup of coffee and d represents the price of a doughnut, which equations could be used to determine the cost of the coffee?

• 10c + 5d = 14.25

  5c + 10d = 16.50

• 10c + 5d = 16.50

  5c + 10d = 14.25

• c + d = 10

  5c + 10d = 16.50

• c + d = 5

  5c + 10d = 16.50

You can work no more than 41 hours each week at your two jobs. Housecleaning pays $5 per hour and your sales job pays $8 per hour. You need to earn at least $254 each week to pay your bills. Let h=housecleaning job and s=sales job. Write a system to represent the situation.

• h + s ≤ 254

  5h + 8s ≥ 41

• h + 41 ≤ s

  5h + 8s ≥ 254

• h + s ≤ 41

  5h + 8s ≥ 254

• h + s > 41

  5h + 8s < 254

What is the slope and y-intercept of the table?

• m=-2/5 b=10
• m=5/-2 b=0
• m=5/2 b=-4
• m=2/5 b=5
