Hi,
the standard slope-intercept form for an equation of a line is y = mx + b  where m is the slope and b the y-intercept.
  {{{y= green(5/2)x-4}}},  m = {{{green(5/2)}}}, y-intercept is (-4)
Plot Pt(0,-4)  <u>Note: as y increases 5, x increases by 2</u> , P(2,1) on the Line as well
Plot Points and connect with Line {{{y= green(5/2)x-4}}}
