The equation is given in standard form (one of them). A linear equation in the standard form Ax+By=C has a slope highlight%28-A%2FB%29. The y-intercept can be found setting x=0 and solving for y; which will give A%2A0%2BBy=C, highlight%28y=C%2FB%29.

Hi,

the standard slope-intercept form for an equation of a line is y+=+highlight_green%28m%29x+%2B+highlight%28b%29

  where m is the slope and b the y-intercept.

4x+9y=47   Solving for y

+y+=+%28-4%2F9%29x+%2B+47%2F9+

slope = -4/9  and the y-intercept is 47/9
