Graph 1 and Graph 2 represent relationships that have different rules. Based on the information in Graph 1 and Graph 2, which statement is true?

• Graph 2 represents a multiplicative relationship because each x-value is multiplied by 10 and the graph includes the ordered pair (0, 0).

• Graph 1 represents a multiplicative relationship because each x-value is multiplied by 3 and the graph includes the ordered pair (0, 0).

• Graph 2 represents an additive relationship because a value of 10 is added to each x-value and the graph includes the ordered pair (0, 0).

• Graph 1 represents an additive relationship because a value of 3 is added to each x-value and the graph does not include the ordered pair (0, 0).

For every 2 hours, there are 7,200 seconds. Which equation best represents the number of seconds, s, in a given number of hours, h?

• s = \frac{1}{3,600} h

• s = 3,600 h

• s = h + 3,600

• s = 3,600h

Two equations are shown. y = x - 5 y = -5x Which statement describes the relationships between x and y in the two equations?

• In the equation y = x - 5, the value of y is -5 times the value of x, and in the equation y = -5x the value of y is 5 less than the value of x.

• In the equations y = x - 5 and y = -5x, the value of y is -5 times the value of x.

• In the equation y = x - 5, the value of y is 5 less than the value of x, and in the equation y = -5x the value of y is -5 times the value of x.

• In the equations y = x - 5 and y = -5x, the value of y is 5 less than the value of x.
