(1)
Where:
- Temperature, measured in degrees Fahrenheit.
- Temperature, measured in degrees Celsius.
If we know that , then its equivalent temperature on Celsius scale is:
The temperature on Celsius scale for 86 ºF is 30 ºC.
For the X intercept you set y = 0 and solve for x
Y =
x + 9
0=x + 9 subtract 9 from both sides
-9 =
divide both sides by 3
-3 = -8x divide both sides by -8
= x
X-intercept = (, 0)
Y =
0=
-9 =
-3 = -8x divide both sides by -8
X-intercept = (
