1. ____ variables respond and are graphed on the __ axis.

a. dependent...x
b. dependent...y
c. independent...x
d. independent...y

Explanation:

• Question 6: Newton's first law of motion states that objects at rest stay at rest, and objects in motion stay in motion unless acted upon by an unbalanced force. Balanced forces result in no change in motion.
• Question 7: Manipulated variables are the independent variables that the experimenter changes, and they are graphed on the X - axis.
• Question 8: Dependent variables respond to the changes in the independent variables and are graphed on the Y - axis.

Answer:

• Question 6: C. Rest...motion...unbalanced
• Question 7: C. independent...X
• Question 8: B. dependent...Y
