The slope of the $T_{f}$ vs. $T_{c}$ plot is 1.8 (= 9/5) and the y-intercept is 32°F. The slope of the $T_{c}$ vs. $T_{k}$ plot is 1, and the y-intercept is −273°C.
Straight line equation: $y = mx + b$, where m is the slope of the line and b is the y-intercept. For the $T_{f}$ vs. $T_{c}$ plot: $T_{f}$ = (9/5)$T_{c}$ + 32 The slope of the plot is 1.8 (= 9/5) and the y-intercept is 32°F. For the $T_{c}$ vs. $T_{k}$ plot: $T_{c}$ = $T_{k}$ − 273 The slope of the plot is 1, and the y-intercept is −273°C.
