Question 770593
Parallel lines have the same slope.  y=mx+b is the slope-intercept form of a line.  m is the slope.  <P>
x+3y=5<P>
3y = -x + 5
y = -x/3 + 5/3.  The slope is -1/3.<P>
The slope point form of a line equation is y - y(1) = m(x-x(1)) where m is the slope and (x(1),y(1)) is a point on the line.  Plug in the info.<P>
y-1 = -1/3(x-(-4) <P>
y-1 = -x/3 -4/3<P>
y = -(1/3)x -1/3
