Question 80854
Write an equation in standard form for the line parallel to x - 2y + 7 = 0 and contains the point (-4,0).
----------
The given equation can be written in the form y=(1/2)x+7/2
------------
so the equation you want has the same slope=1/2
The form is y=mx+b where y=0,x=-4 and m=1/2; solve for "b" as follows:
0=(1/2)(-4)+b
b=2
EQUATION:
y=(1/2)x+2
Now put it in standard form which is ax+by=c.
Multiply thru by 2 to get:
2y=x+4
x-2y=-4 is the equation in standard form.
