Question 1204058
Pick any two points from the line which are easily readable on the graph.  

How about these two:  (-5,2) and (5,6).
Slope  {{{(6-2)/(5-(-5))=4/10=2/5}}}; and actually you can easily also read the line's y-intercept, so to use slope-intercept form:   {{{y=(2/5)x+4}}}.


That's actually using three points.  Two for the slope and one more because it is y-axis intercept.  You COULD use JUST TWO POINTS and go direct from point-slope form.
