Question

What is the slope of the compass needle (the bottom red line)?

Answer 1

176/317

Explanation:

The formula for slope is
`(y2 - y1)/(x2 - x1)`, which means you have to subtract the second point's y coordinate (286) minus the first point's y coordinate (110).

Now you have
`(286-110)/(x2 - x1)` or
`(176)/(x2 - x1)`.

Now you have to do the same for x.

446 - 129 = 317, which gives you the final answer of

`(176)/(317)`, or about 0.555.

Hope this helps :)
