How to find slope and y intercept from the equation ax+by=c?
melisa1 [442]

solve for "y" so it is in the form y = mx + b.   "m" is the slope and "b" is the y-intercept.

ax + by = c

      by = -ax + c          <em>subtracted "ax" from both sides</em>

       y  = (-a/b)x  + c/b     <em>divided both sides by "b"</em>

Answer: slope is -a/b    and y-intercept is c/b
