----------------------------------
Your answer would have been correct if the word "perpendicular"
had been "parallel".
So you have confused "perpendicular" with "parallel"
Things to remember:
1. Parallel lines have EQUAL slopes.
2. Perpendicular lines have slopes which are formed by
taking the reciprocal and changing the sign.
The slope of y = -3x + 1 is -3
Therefore a line which is perpendicular to it will have
the slope which is formed thusly:
Take -3.
Write it as
Invert it as
Change the sign and get
So the slope of a line PERPENDICULAR to the line whose
equation is y = -3x + 1 is
Now use the form:
y = mx + b where m = and b = 5
y = x + 5
That is the PERPENDICULAR line's equation.
