The relationship between celcius and fahrenheit of measuring temp is linear. find a linear equation relating c and f if 0c corresponds to 32f and 100c corresponds to 212f. use the equation to find the celcius measure of 70f?
ok guys i'm stuck on this
i have attempted to do it myself and will display below what i have done
i paired it up
(0,32)
(100,212)
(x, 70)
so i tried finding the slop first
212-32/100-0 and got 9/5
then i just set it up as so
y = 9/5x -32
because the y-int is stated up to at (0,32) and "x" in this case represents fahrenheit (f)
but my answer is wrong according to the book
what am i doing wrong?
