Steps for Making and Interpreting a Graph

The scale can be different for each axis. Once a scale is chosen, keep it consistent. Don’t start out using a scale of 5 units and then switch to 10 units when the data doesn’t fit. 1.Choose a scale for each axis.

2. The format for the title of the graph is “y-axis variable vs x-axis variable”.

3. Determine the shape of the graph. If the points are roughly in a straight line, draw the line of best fit. DON’T connect the dots! If the points form a curve, draw the best-fit curve. Possible Shapes: LinearParabolicHyperbolic

4. Interpreting the Graph ShapeLinearParabolicHyperbolic Relationship “y” is directly related to “x” “y” is directly related to “x” 2 “y” is inversely related to “x” Equationy = kxy = kx 2 y = k/x
