slope and intercept form
my problem is:
use the information provided to write and graph the linear equation that gives the number y of degrees Fahrenheit in the terms of the number x of degrees Celsius.
provided information: Ice forms at a tempertature of 0 C, which corresponds to a temperature of 32F. A temperature of 100C corresponds to temperature of 212F.
How do I solve the problem. I know that to convert fahrenheit to celsius to take the temp. in F minus 32 divided by 1.8
Let the x-axis represent the temperature in Celcsius and y-axis represent the temperature in Fahrenheint.
Look at picture below.
The y-intercept is 32 because for 0 celius we have 32 fahrenheint.
The other point is (100,212).
Find the slope,
The y-intercept is 32 as explained before.
-------- = --
Thus, the equation of the line is, i.e. conversion formula from celius to fahrenheit is.
Thanks I understant how you solved it by using the slope formula. changes in y coordinates over the changes in the x coordinates, to get it slope form
