Question 945347: A line L has the equation 22x + 4y = 20.
Find an equation for the line that passes through the point (-10, -15) and is parallel to L.


The slope of the line through (-10, -15) perpendicular to L is
m =

Simplify the given line.
highlight_green%2811x%2B2y=10%29.
Its slope is -11%2F2.

The line parallel to it and containing (-10,-15) is
11x%2B2y=11%2A%28-10%29%2B2%28-15%29.
Simplify that.

Do you know the needed basic fact to answer the second question?
