You first need to find the linear equation<em> </em>[in <em>Slope-Intercept</em><em> </em><em>Form</em><em> </em>of course] of this graph, which is To do this, starting from the y-intercept of you do by either moving two blocks <em>south</em><em> </em>over one block <em>way</em><em> </em>or two blocks <em>north</em><em> </em>over<em> </em>one block <em>east</em> [<em>west</em><em> </em>and <em>south</em><em> </em>are negatives]. This will give you your <em>rate</em><em> </em><em>of</em><em> </em><em>change</em><em> </em>[<em>slope</em>] of 2.
