: write the slope intercept form for an equation of the line parallel to the graph of the given equation and passing through the given point?
3x+9y=1, (3,0) This question is from textbook

You can put this solution on YOUR website!
3x+9y=1
9y=-3x+1
y=-3x/9+1/9
y=-x/3+1/9 this line has a slope of -1/3.
so a parrallel line through (3,0) has the same slope .
now we substitute the (3,0) values for the x & y values in the line formula & solve for the y intercept(b)
0=-1/3*3+b
0=-1+b
b=1 so this line equation is
y=-x/3+1
the graph of these two lines is:
