Question

What positive value of k would make the lines below parallel in the standard (x,y) coordinate plane.
kx+2y=8
18x+ky=12

Answer 1

The slope of the first line is -k/2
The slope of the second line is 18/-k
For the lines to be parallel, the slopes must be equal.

Answer 2

so i solve for k using -k/2=18/-k?

Answer 3

yes

Answer 4

Okay, thank you very much kind sir/ or madam.
