Hi, Here's an interesting problem:

I have 2 lines with slopes and y-intercepts.

I have a third line with just a y-intercept and I need to determine it's slope in the following condition.

The condition:

What slope of the third line creates a triangle with an area of 0.1?

There should be two answers. One on each side of the intersection point of the first two lines.

How would I set this up to take in multiple line data? Can I reduce the calculation of the slope of the third line to one formula?

sample data:

Line 1: 2.41, 120.45

Line 2: 1.94, 134.26

Line 3: ?, 25.45

any help is appreciated...
