Question 62940
fahrenheit=9/5 celsius+32 (a) identify and (b) interpret the meaning of both the slope and the y-intercept.
Another way to wirte this is: F=(9/5)C+32
The slope intercept form of a line is {{{highlight(y=mx+b)}}}, m=slope, and b=y-intercept.
(a) For your equation: slope, m=9/5 and y-intercept is b=32
:
(b) the slope means that each degree fahrenheit is 9/5 a degree celsius.
The y-intercept is the starting point for measurement, in this case, it's the freezing point of water, for celsius the freezing point is 0, however, for fahrenheit it is 32 degrees.
