Consider the line 2x7y1 What is the slope of a line perpend

Consider the line

2x+7y=1

.

What is the slope of a line perpendicular to this line?

What is the slope of a line parallel to this line?

Solution

2x +7y = -1

Re- arranging the equation:

y = (-2/7)x -1/7

slope of line : m = -2/7

slope of line perpendicular to the given

line , m= 7/2

slope of line parallel to the given

line , m = -2/7
