The F and C intercepts are the points at which the line crosses the F and C axes respectively. When the line crosses the F axis, its corresponding C value is 0. Likewise, when the line crosses the C axis, its corresponding F value is 0. To find the F intercept, set C = 0:

C+=%285%2F9%29%28F-32%29 becomes 0+=%285%2F9%29%28F-32%29 solving of F, we get F = 32 when C = 0 (this makes sence 0 degress C and 32 degrees F is the freezing point of water). The F intercept is 32.

To find the C-intercept, set F = 0

C+=%285%2F9%29%28F-32%29 becomes C+=%285%2F9%29%280-32%29+=+-%2832%2A5%29%2F9+=+-160%2F9%29
