Write the equation of the line containing the point (1,2) and parallel to the line 2x + 4y = 1.
--------
Find the slope of the given line:
2x + 4y = 1
4y = -2x + 1
y = (-1/2)x + (1/4)
slope = -1/2
-------
Any line parallel to the given line must have slope = -1/2
-----
Find the equation of the line thru (1,2) with slope = -1/2
Form: y = mx + b
2 = (-1/2)1+b
b = 5/2
-----
Equation:
y = (-1/2)x + (5/2)

2(1)+4(2)=?
2+8=10
2x+4y=10
4y=-2x+10
y=-x/2+2.5
2x+4y=1
4y=-2x+1
y=-x/2+.25
