Equations in Multiple Representations

Which equation identifies the relationship in the table?

• y = 2x - 5

• y = -2x + 5

• y = 2x + 5

• y = -2x - 5

Which of the following linear equations best represents the graph shown?

• y = 10x - 2

• y = -2x + 10

• y = 2x + 10

• y = 5x
• y = x + 5
• y = x + 470
• y = 94x 

Which equation matches the table?

• y = 3x + 9

• y = x + 9 

• y = x + 3

• y = 12x - 3

Two equations are shown below. Which of the statements best explains the relationship between the equations?

• In y = x + 3, the value of y is 3 more than the value of y = 3x.

• In y = 3x, the value of y is 3 times the value of y in the equation y = x + 3.

• In y = 3x, the value of y is three times the value of x, and in y = x + 3 the value of y is three less the value of x.

• In y = 3x, the value of y is three times the value of x, and in y = x + 3, the value of y is three more than the value of x.
