GRAPHING

IDENTIFY VARIABLES Independent Variable- controlled or manipulated variable. Dependent variable- changes due to the change in the independent variable.

Plot the independent variable on the x-axis Plot the dependent variable on the y-axis Determine the range for each axis Spread data along axis as much as possible Number and label axis ( with units) Plot the data points Draw best fit line or curve. Give the graph a title

Direct proportion

FINDING SLOPE: (x2, y2) (X1, y1)

INVERSE PROPORTION Will have a negative slope

Inverse square proportion gravitational force of attraction and electrostatic force between charged particles
