Hi

line that passing through (3, -5) with slope = -(3/7)

Using the standard slope-intercept form for an equation of a line y = mx + b

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

  y = (-3/7)x + b

 -5 = -3/7*3 + b    |using ordered pair (3,-5) to solve for b

-35/7 +9/7 = b

      -26/7 = b  

     y = (-3/7)x -26/7  OR 3x+7y = -26 in standard form
