Answer:
Where T is the hight temperature and t is the day
Explanation:
The table shows that every day the<em> High temperature, T (degrees F) </em>increases 1 unit.
Then, this is a linear function with slope = 1ºF / day.
You can use the point-slope equation to determine the <em>function of the high temperature:</em>
- Point-slope equation:
- Choose any point from the table and m = 1. I will use the first point (1,95)
- m = 1
- x₁ = 1
- y₁ = 95
Substitute:
Make the variables y = T, and x = t:
