Question 45189: How do I write a linear relationship that describes the outside temperature, T, as a function of the number of hours since 8:00 a.m. At 8:00 a.m. the outside temperature was 76 degrees F and each hour the temperature rose 3 degrees? Thanks for your help, I don't know where to start.

Slope: 3
Y-intercept: (at 8:00 a.m., so zero for the y-value) 76
Equation: T+=+3x+%2B+76
where T is the temperature in fahrenheit and x is the hours from 8:00 a.m.
