Question 3353
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:<br>
{{{C =(5/9)(F-32)}}} becomes {{{0 =(5/9)(F-32)}}} 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.<br>
To find the C-intercept, set F = 0<br>
{{{C =(5/9)(F-32)}}} becomes {{{C =(5/9)(0-32) = -(32*5)/9 = -160/9)}}}
