Variable that is measured during an experiment (y - axis)
Variable that is controlled in an experiment (x - axis)
I worked for 5 hours and made $50.
Independent: What did YOU directly control (do)?
Dependent: What happened because of your action (measure)?
EXCEPTION: TIME is always considered an independent variable, even though it may be the quantity measured.
- Straight line
- Equation: y = mx + b
- Direct Relationship
Slope [Steepness of line] = (Y2 – Y1) or RISE (X2 – X1) RUN
- Determine the independent and dependent variables
- Place a dot at the intersection of the two variables
= ( ½ )(6)(14.5)
