Question

What is the slope of the line that passes through (a,b) and (1/a,b)?

Answer 1

slope of the line is 0

Explanation:

(a , b)=(x1 , y1)

(1/a , b)=(x2 , y2)

slope=y2 -y1/x2 -x1

=b-b/ 1/a -a

=0/1-
`a^(2)`/a

=0*a/1-
`a^(2)`

=0/1-
`a^(2)`

=0

Answer 2

slope = 0

Explanation:

Since the y- coordinates of both points are equal, both b

This indicates the line is horizontal and parallel to the x- axis

The slope of the x- axis is zero then the slope of the line is zero
