Steps to Graphing

  1. D.R.Y. M.I.X.-labeling the axes

a) This is where we label the x and y axis with the names of the independent and dependent variables

b) This does not mean to put the letter y on the y-axis and the letter x on the x-axis, nor does it mean to write the word dependent on the y-axis or the word independent on the x-axis

  1. Scale-where we figure out the numbers to use on the axes

a) Find the largest number listed as a D.V. and place it at the top of the y-axis

b) Place the number zero (or the smallest D.V.) at the bottom of the y-axis

c) Divide the largest number in half and place the answer half-way up the y-axis

Repeat a, b, and c for the I.V. and the x-axis

  1. Plot Data-putting points on the graph and drawing a line

a) Find the first I.V. and draw an imaginary line straight up from its location on the x-axis

b) Find the first D.V. and draw an imaginary line straight across from its location on the y-axis

c) Make a dot where the two imaginary lines intersect

Repeat a, b, and c for all I.V. and D.V.

Connect the dots in order
