Which of the following answer choices correctly represent the below equation? If there are multiple correct representations, select each one. y = −3x − 5

• First diagram

• Table with values: x = 2, y = −10; x = 4, y = −16; x = 6, y = −22

• Table with values: x = 2, y = −12; x = 4, y = −16; x = 6, y = −20

• y is the difference between −3 divided by x and −5

Which of the following answer choices correctly represent the below equation? If there are multiple correct representations, select each one. y = −x + 1

• Second diagram

• Table with values: x = 1, y = 0; x = 4, y = −3; x = 7, y = −6

• Table with values: x = 1, y = 1; x = 4, y = −2; x = 7, y = −5

• Table with values: x = 1, y = 2; x = 4, y = 2; x = 7, y = 2

• y is the sum of −1 divided by x and −1

A customer wants a window that is 12 feet tall. You have 76 feet of molding to make the window. How wide is the window ?

(Note: the width of the window is divided into 3 equal pieces)

Answer explanation

4(12) + 4(x) + 2/3(x) = 76

x = 6
